I have a female cat age 3yrs. She has had kittens in the past, so I'm told. I purchased her as a breeder.
I have bred her to my male for her last three heats and she has not gotten pregnant.
She is getting bred , screaming and rolling... but comes right back into heat in about four weeks. What's up ?

I am wondering if she has truly had kittens in the past. I Purchased one of my persians at a redicoulously cheap price because she was just about to turn 2 years old and had still never gone into heat. She finally did go into heat 6 months later. But I had heard that breeding was a bad idea if the female hasn't had a litter before she's 2. So we had her fixed, and she's just a sweet prissy girl now. I hope you weren't led astray by the breeder. Good luck. Blessings!
