How much should an adult cat weigh?

This is assuming the cat is healthy and active.

40 pounds.

12 lbs

i think like 55lbs is good healthy cat

dead weight

My cat-boy qualifies as healthy and active.He weights 15lbs.Have fun but be safe!

and assuming that it is what breed? lolgo by if your cat is shaped like a melon from above.. that would be overweight... Don't go by weight so much on a daily basis.

My stanly weighs about 8 lbs and he is healthy and 1 year old

Well I have 6. Most of them weigh around 10 lbs, but my Bubbis weights a whopping 22 lbs and he is very healthy and active. In fact, yesterday he brought me a woodpecker. So it really depends on their parents.

I found this on Animal Planet:"To determine if your cat is overweight, run your hand along his side. If you can not feel his ribs, it is time to start a weight reduction program. If your cat does not have a waist, that is another indication it is time to start a weight reduction program. "The rest of the article goes on to describe several ways to deal with weight maintenance:http://animal.discovery.com/guides/healthcenter/cats/nutrition/reduction.html

It all depends on the breed of the cat. I think 10 - 20 pounds is average.

it depends on the breed. i have a siamese and my vet said she should be about 9 pounds. i would check with a local vet to make sure.

Healthy and active..I have a cat that is healthy and active...hes a good 12 pounds...but I have a smaller cat and he is a good eight...cats are like humans....go off of body and the build of your cat...

Just like people it depends on their bone structure and length (our height) of the body.I have two male cats at around 12 pounds, 2 females at around 8 (one should be 7) and one female at 7. Sylvie is thirteen and she looks like a fashion model - horrifyingly thin to me and she just had blood work done and an exam and was pronounced perfectly healthy by the vet.

It depends on the breed and build of the cat. My male is a big DSH....he's about 12-13lbs. He WAS 12, but was getting tubby...but since we've switched his food (two meals of canned instead of free-grazing on dry), he's been losing weight. HIS healthy weight is right around 12-13lbs. However, my female is very petite. She weighed 7 1/2lbs. when we got her, but she was real skinny. Just remember that 1 pound is a lot on a cat. I'm thinking once she's done filling out, she'll be around 8-8 1/2lbs.

12lbs some might say 14lbs is ok but its too much bc then they'll be less active & get even fatter! 15lbs or more i would say is wayy too much unless u have the larger type of a cat like the main coon.

male or female?- female 8 or 10lbs.-male 10-12lbs.
