I had a 5 yr old girl chin for a little while and recently put a male in with her. It took them 3 days to warm up to each other and they started mating. It's been 2 weeks and now my female who is a lover and always perky is acting different. She's slowed down a bit and is sleeping a lot more and my male is being very protective of her. They cuddle together in my bottom dresser drawer and when i reached sown to pet my girl, Buddy (the male) barked at me and tried to get between me and her........ Is she sick or maybe pregnant or something? I'm not exactly sure what to do
