Owner’s guide

International Cat Care has created a resource (available at icatcare.org/advice/catcarer-guides) explaining to owners what to expect if they are considering volunteering their cat as a blood donor or, indeed, if their cat is requiring a blood transfusion. Not every cat can be a blood donor and vets will be looking for cats:

Aged between one and eight years old.

Weighing over 4.5kg (but not overweight).

That are up to date with vaccinations, worming, and flea treatments.

That are not on any medication.

That test negative for some diseases.

With a calm temperament (not stressed by the veterinary environment or travel).

Well-informed decision-making around the use of blood products in cats requires the vet to carefully balance the benefit to the recipient cat, the suitability and welfare of the donor cat, and ethical justification for the procedure. The aim of these new guidelines is both to facilitate this process and help to ensure that the health and well-being of recipient and donor cats are equally prioritised.

While we all want the best for our cats when they are unwell, the decision to provide a blood product is not straightforward. You should feel you can discuss your concerns with your veterinarian and decide together if this is the most appropriate treatment for your cat.

A blood transfusion can be a potentially lifesaving procedure, but in each case, the risks and benefits for both the recipient and the donor cat must be carefully balanced.
