F 5th - that's a rumour spread by cats! - Mostly mine!
I always wondered what those cats talk about when they get together
There seems to be a split in the vets opinions of this. Holistic vets are of the opinion that adult booster shots are not needed, where as the other vets feel annual shots are needed.
All I know is when I was a kid, manymanymanymany years ago, our cats never had annual shots and they all lived long healthy lives.
I've given Marmie my cat annual shots for the last 3 years. It's always a very traumatic time for her because she hates riding in the car and going to the vet. Then when she gets home she mopes around the house listless for 3-4 days from the effects of the shots.
I think the holistic vets might be on to something.
