Hi there I got my little double Rex on August 31 (11 days ago) and I she is about 6-7 weeks old. She was in with boys so knew she could be pregnant and guess what? I'm petty sure she is!! Her cage mate now (not her biological sis) is younger but was also with boys so who knows, anyway my double Rex, peach, is vigorously nest-building, has bit me hard twice and has a bulging tummy, oh and she is sleeping all day. So ya, preggo! I gave her some cat food as extra protein but her due date is coming up and if she's aggressive now she will be very aggressive after her babies but she is in a four-story cage with a sister how and when should I move her??? Also any advice on the general subject appreciated.
