I woke up 28 days ago to a strange Tom in my house mating with my female...I couldn't get him out the house. My female was rolling round flirting afterwards...eventually got him out with the hoover noise. She's nearly 2 never been in heat before then. Last week (day 21) her nipples looked a lot bigger and pinker (usually flat and white) no noticeable weight gain though I've made kitten food available at all times (though my fixed males tend to eat whatever's in the bowls) I will be taking her to the vet (told after 40 days for ultrasound)
