Shedding calicivirus.

Species: Cat
Breed: siamese
Age: 1-2 years
Hi can I breed from a cat shedding FCV? She has no symptoms but doen't seem to be able to get rid of it. We have tried interferon treatment unsuccessfully.
Thanks

Dr. Marie replied:

This is a tough question. Most cats with calicivirus will eventually get rid of the organism, but approximately 30% can go on to become carriers of the virus. Unfortunately, when that happens there is nothing we can do to make them not carriers.

Regarding breeding, it is not believed that a cat who is a carrier of FCV will genetically transmit the virus to her kittens. However, I am suspicious that it is possible that the ability to become a carrier can be spread through genetics.

The other concern though is that once the kittens are born, if the mom comes down with a bout of calicivirus then she can spread it to the babies directly.

So, there is no perfect answer to your question. Given the choice, however, I would not breed this cat.
