Aww, sweet. I used to have many rats. My favourites were my buck rat, Boots, he got to be a foot long not including the tail, and my hairless rat, Saggy. Rats are sweet and clean animals and smart. Boots was after Saggy, and I wanted another hairless. I wanted to breed Boots, but he was so big, he suffocated and squashed any females I put in the cage. My sister had a rat, Socks, that was just a little bit smaller than Boots who had a litter a several weeks before, and she offered to let them mate, I could have any hairless that was born. No hairless, still picked a rat after it was weened. My sister removed Boots the morning she saw Socks had the litter. But a few days after the babies were weened, we found out Socks was pregnant again. Like cats, rats breed QUICKLY! Lol. That litter produced no hairless, either. But all the babies we seperated soon all the females were showing signs of being pregnant. It was scary! Soon my sister had over 100 rats, she sold most, the rest she let loose 5 miles from the house. 1 week later, my nephew was taking a load of his laundry to the apartment laundry mat, saw something and screamed, he was young didn't really like the rats, ran to my sister, she went to check, and saw one of the rats she released a week before behind a dryer! She took him into the apartment and named him Smartypants.
