Hi! My female kitten is 12 weeks old today. I have a question about heat & fertility. Everyone (including the vet) told me to get her fixed around 4-5 months at the earliest because she can not have kittens til about 5-6 months. I have 2 adult males & 2 males. (One age estimated at 14-15 weeks & the other was said to be 8 weeks though i think they lied because he & his siblings are SMALL & he should be 11 weeks today & he's still tiny compared to the older 2) anyway, mooch (adult male) likes to groom Katsumi. Should i be worried he'll knock her up? She shows no signs of heat merely wants to play eat & be groomed.
