I also don't see the need for a six month visit. Sirrahbed makes an excellent point - my cats also get stressed out when they have to go to the vet. One of the reasons I've chosen my current vet is because it is so close to my house.

My little girl Jan has peed or pooped in her cat carrier the last two times that I've taken her in. Sid moans like I'm stabbing him. So yes, I try to keep vet visits to a minimum.
