Re: Annual Vaccinations
The trouble is that many thousands of indoor cats become outdoor cats, even if by accident and/or temporarily. It certainly is not an exception to the rule, it happens a lot. Being an indoor cat has it's health risks also, particularly as they get a bit older, and the sedentary indoor lifestyle takes it's toll. My barn cats seem more than happy to risk the dangers of the outside world to enjoy . . . well doing what cats do naturally. Cats have a different scale of what they hold dear to themselves than humans do, though I'll concede if someone wants to keep a cat indoors 24/7/365, I have no issue with it. Cats are pretty adaptable
I'll concede than in urban and suburban settings, indoors is probably the best way to keep them, albiet maybe not best for the cat so much as to spare human sensibilites and property rights and other irresponsible pet owners free-roaming animals, but I have acreage and barns that need mousing.
But to get off my tangent here,
vaccination frequency and protections are something that should be discussed rationally with ones Vet. A lot of unwanted kittens are dumped at our shelter by people who didn't spay their indoor cat because it never escapes . . . well, except that one time.
