I just had the biggest scare of my life!!!!!!! I went to clean out Wrinkles cage. I put her in the bathroom while I was tidying. Well when it was al fixed up I left a few old toilet paper pieces in there as well as a few pellets and carefresh withher scent and made sure to rub the babies in it. I made the new nest and set the babies in it. When I put Wrinkles back she was really nervous. This is her first litter so she doesn't know all the ropes of parenting yet. She immediately took on the kittens in her mouth and started searching frantically for her old nest. She was doing this for at least 5 minutes with the poor baby in her mouth. I could not disturb her because it would make it worse and her more stress so I let her get rid of her stress and she finally settled down. She went to the nest and started cleaning the babies making sure they were ok. Then she covered them up like crazy, you couldn't even see them anymore lol. She was so thankful for them to be in her nest. She is a really good mom. Now she is feeding them all and they are starting to get their color and have their markings show. What a scare though for that one baby. It wasn't hurt, rat moms are very gentle and it looks worse than it is, but you would think I would be used to it by now, lol. Nope not me,I still worry as much as ever!
