Asim and Isha have not been into the vet for a check up or shots since the late summer of 2001. Though I will probably be bringing them into the vet sometime this year once I can decide on one that I like. We just moved to a new town about 5 months ago.
I take my cats in whenever they need their shots, or if they fall ill, or just any other concern I might have where they will need to be seen by a vet.
Some people only bring their cats in for shots every 3 years, some people only bring their cats in PERIOD every 3 years. And don't do the yearly check up.
I was a very bad momma last year by not bringing my cats in for a check up, but they are still so young, they don't have problems which are more likely to develope as they become seniors. However they will be seeing a vet this year.
I would say, that most people, your average pet owner brings their pet cat in once a year, and gets all the shots, once a year.
