Pet Passport scheme changes

As from 1st January 2012, the requirements for the pet passport scheme changes, for both dogs and cats. Pets will still need to be microchipped and have a rabies vaccination, but will no longer require a blood test for rabies. Pets will need to wait 3 weeks after the rabies vaccination before entering the UK. On return to the UK, pets need to be treated for tapeworm by a veterinary surgeon, 24-120 hours (1-5 days) before embarking for the UK (by ferry or air).

Pets travelling to the UK from unlisted countries outside the EU will need to be microchipped, vaccinated against rabies, pass a rabies blood test and then wait 3 months in the country of origin. See www.defra.gov.uk/wildlife-pets/pets/travel/pets/ for further information about the pet passport scheme and countries included.

Our vets can issue pet passports at our Hounslow and Ealing surgeries. Please see www.youngvets.co.uk for contact details.

Cat poisons

The most common poisons encountered by cats are

  1. Lillies
  2. Dog flea products containing permethrin
  3. Aspirin and other salicylates
  4. Paracetamol
  5. Antifreeze- Ethylene Glycol
  6. Liquid Potpourri
  7. Glow sticks
Lilly Poisoning
Many people are not aware that a common plant such as the Lilly is extremely poisonous to cats. All parts of the plant, stem, flowers and pollen are poisonous.

If your cat ingests any part of a Lilly plant you should seek immediate veterinary attention, as it can cause acute kidney failure.

After a cat has eaten part of a lily plant, signs of stomach upset (vomiting, lack of appetite, or lethargy) may be present. Clinical signs may be seen from 2 hours to 4 days after ingestion  of the plant, and  signs of kidney failure may begin which can include loss of appetite, depression, vomiting, and occasionally lack of urination.

With early treatment  (within 18 hours) with aggressive decontamination (making the cat sick and giving activated charcoal) and fluid therapy for 48 hours the prognosis can be good with  complete recovery.

Luckily lillies do not appear to be toxic to dogs or rabbits.

Dog Flea products containg pyrethrins

Cats are much more sensitive to pyrethrins than dogs.  Poisoning usually  occurs when a spot on dog flea product is administered mistakenly to a cat. These pyrethrin containing spot on preparations are the ones commonly found in pet stores and supermarkets.

Signs of toxicity are varied and include excess salivation, vomiting, weakness, excitability, tremors, seizures.

Treatment involves controlling seizures with phenobarbitone or gas anaesthesia,  (they are less responsive to diazepam),  intravenous fluids, maintenance of body temperature and glucose levels, and washing the product off the skin with washing up liquid.  Signs may persist for 1-4 days.

The prognosis can be good with early and aggressive treatment.

Occasionally cats may also show scratching at the application site , chewing feet or extremities, and nervous behaviour due to a problem called paresthesia. This is treated with decontamination of the site with washing up liquid, and application of vitamin E oil to the application site.

Aspirin and salicylates


Aspirin (acetylsalicylic acid) is present in many over the counter analgesic ointments, as well as the common tablet form. Non aspirin salicylates are found in topical acne creams, lotions, sunscreens, facial masks, and make up, deep heat, Ralgex cream and Boots pain relief heat rub.

Toxicity to cats with aspirin is possible with ingestion of more than 30mg per kilogram weight of cat. Thus for an average 4kg cat 120 mg of aspirin may be toxic.

Signs of toxicity can appear hours to days after ingestion,  causing vomiting, diarrhoea and gastrointestinal ulceration with blood in the vomit or black faeces.  Collpase, fever, tremors seizures, bone marrow suppression and cerebral oedema may also be seen.

Treatment involves making the cat vomit or washing out the stomach, followed by activated charcoal. A course of gastro-intestinal protectants (sucralfate and h2 blockers) may be needed for 10-14 days. Intravenous fluids and regulation of body temperature may also be needed.

Paracetamol

Paracetamol is highly toxic to cats at  a dose rate of 45mg/kg or 180mg for an average 4kg cat), and symptoms include blue (cyanotic) mucous membranes (gums, or tongue) and difficulty breathing.  later symptoms include blood coloured urine and jaundice (yellow colouration of skin and mucous membranes due to liver damage).

Treatment includes making the cat vomit, or washing out the stomach, oxygen therapy, gastric protectants (activated charcoal),  intravenous fluids.

The prognosis is generally poor, even with treatment.

Ethylene Glycol   (Antifreeze)

Antifreeze products that are used in car radiators and  sometimes brake fluid, contain ethylene glycol that is highly toxic to cats. The substance has a sweet taste and may be drunk or the cat may get it on their feet and then lick it off.

It causes vomiting, a staggering walk and kidney failure. Treatment involves decontamination of the cat and hospitalisation and intravenous fluid therapy. Early treatment can give a full recovery but  unfortunately if kidney failure develops it can be fatal.

Liquid potpourri

Cats exposed to liquid potpourri can develop server skin , eye and mouth lesions. They contain essential oils and cationic detergents that are toxic to cats.

Treatment is usually successful but may require several days of hospitalisation and supportive care.

Glow sticks

Glow sticks when broken contain a substance that is irritating to cats and may cause excessive salivation, agitation and vomiting.  The symptoms are usually shor-lived lasting only a few minutes. Normally washing any part of the coat contaminated and giving milk or tuna juice to dilute the taste is all that is required.

Cat heart disease – veterinary ultrasound scan

Cats can develop heart disease called cardiomyopathy. The most common form is caused by a thickening of the heart muscle (hypertrophic cardiomyopathy).

Unfortunately cats often hide this problem very well, and may show no symptoms until seriously ill.  Your vet may be able to hear a heart murmur or irregular rhythm, which could indicate a problem.  It is important to have regular check ups (at least yearly) so that your vet can check for problems like this. The best way to diagnose this disease is by ultrasound scan.

This video shows a normal cat heart on ultrasound scan. You can see the moving heart valves (mitral valves) of the left side of the heart towards the bottom of the picture. These  valves are between the top chamber called the atrium and the bottom chamber called the ventricles.

Cat nail clipping

Cat nail clipping is possible at home, as long as you have a little knowledge.

  • First of all what type of nail clippers should you use ?

These nail clippers are the type that i use most commonly in practice, but there are smaller variations on this design that also work well. The type of clippers that i would avoid are the “guillotine” type.

  • How do i clip the nails ?

This is ideally a two person task, and is easier performed on a table at about waist height.  While one person holds your cat still, you can the hold a paw and clip the tips of each nail.  If you look at the diagram below you will see an area of the claw marked with dotted lines called the ungual process. This is the sensitive part of the nail that contains sensory nerve endings and a blood supply (also called the quick), and should NOT be cut.

anatomy of cat claw

When you look at the claw from the side, often the tip of the nail is much finer, and it then thickens as you move towards the base. This thicker region contains the blood vessel and should be avoided.

So if you can see the fine fip of the nail this is the part to be clipped.

  • How often should i clip my cats nails?

If your cat goes outside,  or uses a scratching post you may never need to clip your cat’s nails. However the nails can  grow quickly just like our own nails , and so can be clipped whenever the sharp points have regrown.  If in doubt clipping every 3 months should be fine.
