Grissom at 3 months old

This handsome fellow is Grissom, a lively 3 month old kitten. Like the TV character he is named after, he is extremely inquisitive and tenacious.

Grissom belongs to a good friend of mine and enjoys all the luxuries that a cat-loving household can offer. But unfortunately he had a very bad start in life when he succumbed to cat flu as a young kitten in a rescue cattery.

Cat flu is a viral illness which can affect cats of any age and breed, but the very young are most susceptible. Kittens born to unvaccinated mothers are especially vulnerable as they do not start life with good levels of immunity. The main strains of cat flu are feline viral rhinotracheitis and feline calicivirus, but there are other viruses and bacteria causing similar symptoms.

The signs of cat flu are very similar to flu in humans (although it is not caused by the same viruses). Cats will sneeze and have runny noses and sticky eyes, go off their food and generally look unwell. They are likely to have a raised temperature and become lethargic. Some strains also cause mouth ulcers. As a result of not eating and drinking they can quickly lose weight and become dehydrated. Longer term effects can include damage to the eyes or chronic snuffles. Most cats will get over the illness in 2-3 weeks, but unfortunately some will die of cat flu, sometimes in spite of receiving all the treatment possible. After infection, some cats will become carriers, which means they will intermittently shed virus, acting as a reservoir of infection for other cats. Known carriers should be isolated from other cats.

Flu viruses spread very easily between cats as virus particles are shed in the saliva and the secretions from the nose and eyes. They spread when the cat sneezes, and they can also survive on bowls and litter trays, and on the hands and clothes of people dealing with them. Disinfection is an important part of prevention of spread, and in a multi-cat household or a cattery, any affected cats should be isolated.

2 weeks of constant nursing care were essential to Grissom's recovery

Viruses themselves are difficult to treat and anti-viral drugs are not generally available, but most cats with cat flu will also have secondary bacterial infections of the chest, throat or eyes, which can be helped with antibiotics. In serious cases they may also need to be given fluids by a drip. Nursing care is extremely important to their recovery. I don’t think Grissom would be here today if he hadn’t had round the clock nursing care, first of all at his vets and then at home, for nearly 2 weeks. This includes cleaning the eyes and applying drops, syringe feeding, steam inhalation to clear airways and general TLC. All of this has to be done in isolation from other cats. Now that Grissom is better, he is a very well-socialised cat who enjoys human company.

Routine vaccination against cat flu is the best way to prevent it. There isn’t a 100% guarantee because of the different strains involved, but it will greatly improve the odds.  Rarely, vaccination itself can have some unwanted side effects, but I believe that the small risks involved in vaccination are outweighed many times over by the benefits. Kittens can be vaccinated from about 9 weeks of age, with the primary course requiring two injections a few weeks apart, and then an annual booster.

Boarding catteries and breeding catteries have to be particularly careful to prevent outbreaks of cat flu, which happens much more commonly where many cats are housed together. It is preferable to house cats in smaller numbers, with solid “sneeze barriers” between them to prevent spread. Boarding catteries will not accept cats which have not been vaccinated.

Cat flu is still one of the most common viral illnesses of cats and can be very serious and unpleasant. It is well worth taking all possible steps to prevent it.

Most people are aware of tetanus (“lockjaw”) either through having vaccinations at the health centre or perhaps if they own a horse which has to be vaccinated against the disease.

Both humans and horses are genetically susceptible to tetanus and a particularly risky combination of events is when a gardener receives a wound whilst handling horse dung. The tetanus-producing organism (Clostridium tetani) is found naturally in soil and horse manure and can exist as spores for many years.

Dogs and cats only rarely get tetanus. In fact most vets will only see one or two cases in their professional lifetime but once seen, never forgotten. Because of the years I spent in animal welfare practice with a high turnover of cases, I managed to see two dogs and two cats with the condition during a period of 37 years.

Dogs get the condition much more seriously. The disease affects the nervous system by producing a toxin which causes all the muscles to eventually go into spasm so the dog becomes almost as rigid as a rocking horse and the muscles of the mouth are drawn back in what is known as a sardonic smile (risus sardonicus). Eating, drinking and even blinking become almost impossible and in dogs the condition is often fatal if intensive care is not administered early enough.

Cats are a different proposition. The tetanus bacteria are often introduced from a wound or a fight and the muscle spasm is usually localised in a hind leg. Over a period of a few days the leg becomes completely rigid and can only be trailed behind the cat.

Amber was a three year old cat who enjoyed going out at night. Inevitably she got involved in a few territorial fights on her travels. Her owner brought her in because she was obviously lame.

When I examined her, I found another cat’s canine tooth embedded in her back leg. This deep puncture had allowed the tetanus organisms to become established in her damaged muscle tissue and the toxin then affected the muscles of the whole leg.

I started Amber on a combination of penicillin, a drug called metronidazole and diazepam to relax the muscles and reduce the discomfort for her. It took about a week for the treatment to start to work and then there was a gradual relaxation of the muscles. By three weeks after she had been diagnosed, there was no trace of stiffness. During all this time, Amber continued to eat well and was only inconvenienced by the lameness.

After the first case I saw in a cat, I reported it to our professional journal, The Veterinary Record. A few people wrote to me to say that they had seen cases in the tropics where cats had been neutered in less than ideal surgical conditions and without the benefit of antibiotics.

So while tetanus is a pretty rare occurrence in the cat and cannot be vaccinated against, perhaps this case will remind us that the potential for tetanus is always present in the environment and that we should make sure that our own tetanus vaccinations are boosted every ten years and that we get a dose of antitoxin whenever we have a contaminated puncture wound.

Horse owners should consult their vet about keeping up booster vaccinations against tetanus. Intervals vary so ask your vet for advice. It is important to remember that the antitoxin given when a horse has treatment for a wound will only give up to three weeks protection if the horse has not been vaccinated against tetanus.

I often find myself sympathising with my patients, and feeling for their distress and pain when they are suffering from illnesses or injuries – and never more so than when their problem involves their eyes. There’s something about injuries and diseases of eyes that really affects me more than almost any other type of problem and I can really empathise with how my patient must be feeling. Having an ulcer or other injury to an eye must be horribly painful, not to mention the psychological impact of dealing with the loss of some or all of your sense of sight.

When Sylvester the cat came into the consulting room last week and clambered miserably out of his wicker basket, my heart sank and I felt an immediate sense of shock and distress when I saw his problem. His left eye was barely recognisable, with a large grey ulcer dominating the cornea and angry red blood vessels invading the usually clear surface of the eye from the sides. This was not Sylvester’s first visit to the surgery for this problem, but it was the first time that I’d seen him, and I immediately knew that we needed to do something drastic if we were going to save his eye – and bring his obvious suffering to an end. Looking at his records it was clear that this ulcer had been grumbling on for a couple of weeks by this stage, and despite ongoing treatment with medicated drops it was getting worse rather than better.

At this stage we had a couple of options to consider. One was to refer Sylvester to an eye specialist, but this was quickly ruled out by his owner on the ground of cost and lack of pet insurance cover. The second option would be to continue with medical therapy, taking a swab to find out exactly which bacteria were causing the ongoing damage and preventing the ulcer from healing and potentially changing the eye drops once these results were known. The downside of this course of action was that it would do little to alleviate Sylvester’s discomfort in the short term, but after talking to his owner and explaining that the only other option would be surgery to remove the eye, we agreed that we would try this first.

So I took a swab from Sylvester’s eye and sent it away to the laboratory to see what they could tell us about the infection. While we waited for the results we did what we could to manage Sylvester’s discomfort with painkillers and anti-inflammatories, and then as soon as the results were in we started him on an aggressive course of antibiotics that were targeted specifically at the bacteria the swab had isolated. At this stage I was still optimistic that we could save Sylvester’s eye, but unfortunately things didn’t work out as planned and despite our new treatment regime, the ulcer stubbornly refused to respond and after a week of treatment it became clear to me that we were left with only one option – to remove Sylvester’s eye.

Breaking this news to his owner was not easy, but she did appreciate that it wasn’t fair to let him continue to suffer as he was doing given the now very slim chance that we would be able to save his eye. After a couple of long – and emotional – consultations, we agreed to go ahead and last Friday Sylvester came into the surgery for his operation.

Removing an eye is an operation I really don’t enjoy, as I can’t help but really feel for the poor animal that is losing such a crucial part of their anatomy, and the operation itself is also technically tricky and pretty gruesome. Sylvester’s operation went as well as I could expect, but it was not one that I finished with a sense of satisfaction – I felt good that we had brought Sylvester’s suffering to an end, but I also felt as though we’d failed him by having to resort to such a procedure.

One of the most common problems small animal vets see in dogs, almost daily, is anal gland trouble. Although cats have anal glands too, they rarely cause trouble.

All dogs have two anal glands (or anal sacs) situated just inside the rectum, one on each side. The cells which line the glands produce a foul-smelling substance which dogs use as a territory- marking device. When the dog passes faeces, the anal glands get squeezed and the scent is deposited as well. The normal anal gland is about the size of a pea in a small dog or a grape in a larger dog, depending how full it is. The anal gland secretion travels down a short tube or duct to enter the rectum. It can be liquid or more like a paste in texture.

When everything is working properly, the anal glands empty naturally and cause no trouble. Unfortunately it is quite common for the glands to become over-full or for the duct to become blocked, and then they cause discomfort. When they do not empty naturally, they are described as impacted and the condition is called anal gland saculitis. The dog will then try to lick at the area or will “scoot” their bottom along the ground in an attempt to relieve the irritation. This may well make things worse and allow infection to enter, leading to an abscess. If things get this bad, the main sign will be pain, or a blood-stained discharge if it bursts.

Dogs who suffer from this problem regularly will tend to show similar symptoms each time. As well as scooting or licking under their tail, dogs which cannot easily reach the area may chew themselves on their back or their feet instead. Sometimes the first sign of trouble is a distinctive and very unpleasant fishy smell. Owners will usually recognise the signs in their own dog and have the glands emptied promptly by their groomer or vet.

Luckily the anal glands can be emptied fairly easily once the knack has been acquired, and as long as there is no infection present, this will be all that’s necessary. If an owner feels confident to do this job themselves, they could ask the vet to show them how to do it. It is not the nicest job in the world, because of the smell and because of the uncanny ability of the contents to squirt in unexpected directions! On the other hand, it is quite rewarding to bring almost instant relief to the dog in most cases.

If an abscess forms, it may have to be lanced and flushed out, and antibiotics will be needed. Pain-killers may also be advised as an abscess is very painful.

When anal glands cause repeated problems it is sometimes advisable to have them surgically removed under anaesthetic by your vet. Like any other operation, the advantages of this type of surgery need to be weighed up against the possible risks. It would not be recommended in cases where symptoms are mild and easily sorted out by manual emptying.

Prevention may be possible by changing the diet or increasing the amount of fibre to make the dog’s stool firmer, for example by adding bran to the diet. Anything which causes a soft or runny stool can cause anal gland problems.

Further advice can be obtained from your own veterinary surgery.
