My cat stopped purring when he was 6 months old. He is now a year and a half . He was neutered around the same time as the purring stopped. The Vet gave him a clean bill of health and can't give me a reason why he stopped. He's very independent and the only human he warms up to is my husband. He gets along very well with my other cat (a female) we adopted about 4 months ago and his best buddy, our 10 year old rottweiler, who he sleeps with every night. He's never been a real friendly cat and will let you know if he does not want to be touched. I know there was no abuse because we have had him since he was 6 weeks old. My family says I spoil him too much and I constantly tell him how much I love him. He's a american shorthair and is black and white.  I've been told he thinks he's a dog!!!  Can anyone help???

I had forgotten that he did have surgery when he was about 7 months old. His third eyelid became infected and the vet eventually removed it after he tried antibiotic cream which failed to treat it.  Thanks to you who have responded. And I guess your right, I should not take it personally.  A cat is a cat. Though sometimes they act so human. Come to think of it, I know a few humans that act like that too. Thanks again.
