Often your cat will seem 'off colour' for a day or two after its vaccination and the injection site may also become tender and swollen. If these effects do not wear off it is worth taking your cat back to see your vet. If you are concerned about any symptoms in your cat do not hesitate to contact your vet for reassurance or advice.

Infectious disease may not seem very common in cats because most cats are protected by vaccination. Your cat must receive regular vaccinations to be fully protected against these diseases.
