Can I speed up my cat's hair growth?

Are you planning on having him neutered soon? or has that been done already? Coats fill in more after that. I think they also fill in more as adults, but they go thru phases.

I just purchased some conditioner too, that was suggested in the grooming section, I'm looking forward to seeing how that works.

Thanks, he was nuetered three months ago. I hope you are right and I think you probably are about the age part. Perhaps when they quit growing, then their hair starts to fill out more? Anyway, I see these photos of show cats and they all have much longer hair than my kitty, of course I guess you do not show cats until they are older, I do not know and I do not intend to show my cat, I just want him to have as long hair as possible and wonder if these show people know some tricks. I am probably just not being patient enough since I have no experience with longhairs. Since he is only seven months old maybe I just have to wait...

It probably is just a waiting game. Psyche is my first longhaired, too, and her coat seems so much shorter than it should be. She's also only 13 weeks old, so that adds to it, i guess.

Kitten s that are longhairs likely are similiar to dogs in that their coats come in with age ... A high quality diet can help but let mother nature do her thing

Missy is no particular breed but her hair was 2 inches long until she turned 1 then suddenly it grew to over 4 inches.

He may have gone though his kitten moult. It takes about 3 months or more for a Persian coat to grow out...even in this heat, my persian carries a 5" coat!
