I was talking to alot of cat owners and they told me that after they got their kitten's intitial shots, they rarely saw the vet again unless their cat was obviously sick. Is this a good idea? Reason I ask, is our vet always reminds us that our cats our due for their yearly booster shots each year.
Even indoor cats can get out of a tempting open door and other disease carrying things can get in (mice, bats, etc.) At the very least, the rabies shot is a good thing to keep updated. Personally, I'd rather keep them vaccinated than have to worry about accidentally exposing them to things. And some states require the rabies shot. If you ever needed to board the cat or if they have a problem where they need overnight vet care, you would have to update them then. I don't really have a choice because I have pet sitters that care for my dog when I'm away so all my animals have to be up to date on shots for them to come in. But I would do the vaccinations anyway.
I would suggest updating your pets shots yearly. This will also give you the chance to talk to your vet and make sure your pet is getting only the shots you feel it needs. For example my cats are strictly indoors, so they only get rabies and distemper. While some will disagree, because they don't go out I dont get the lukemia shots for them. I don't feel its necessary for them. Also by having a yearly checkup it gives the vet a chance to make sure your pet is in good health and doesn't have any other problems. I know my vet, does a ear, nose and teeth check, she looks for fleas, weight loss, just anything out of the norm for my pets. It will cost you a bit, but its definetly worth it.
