I have two 13 year old cats that we have always had vaccinated yearly - both in good health but slowing down a bit. The last few times they have had their booster both (but one in particular) have been under the weather for a while afterwards and this seems to have got worse year on year.
They barely go outside now and don't come into contact with other cats so I am wondering whether its reasonable to decide not putting them through it is worth the risks. So much conflicting advice comes up in a google search. What have other people done?
I would still like them to have an annual health check even if we decide not to immunise - is any vet likely to do this or will they insist on vaccinations?
