Hello,
When our animal shelter takes in feral cats that turn out to be FIV positive we still let them back to their usual place, if they are truly feral and otherwise healthy. Nothing would be worse for them than to be contained for the rest of their live, always stressed out and afraid.
However if they turn out to be friendly, like yours and like to be touched etc. we try to find a new home – however still with the option to go outside, if they turn out to be not lucky inside.
Before doing so of course they will be treated against fleas, worms, get their cat flu shots, get neutered etc.
Of course they risk to contract FIV to other cats, but for neutered cats it’s lower, as they don’t get into fights that much and don’t mate.
It’s worse for leukemia. Of the last colony we trapped, most were tested positive for leukemia and they looked like it. They had a (very) bad health status and were put down, as they were completely feral.
I can’t recommend a medication for worms however, as the products will most likely be different from where you live and I’m no vet anyway.
Hello,
I have only been able to feel a polyp a few times. Every so often I can do a quick enough oral exam to feel them in the back of the mouth. But even with these I needed to do a sedated exam to be sure. Kittens can get hyperthyroidism which can cause palpable enlargement of the glands on the outside throat area. This is diagnosed and confirmed with a blood test. Please call your vet to discuss these. If finances are a concern call the shelters and rescues to see if there are low cost pet care options available.
