I have had Jasper since he was 7 weeks old. I got him from a hobby breeder at the fair over the summer, and he has an excellent temperament. He is such a dream and exactly what I was looking for. His birthday is May 23rd, which makes him 6 months old. He looks black and white, but he actually has the "otter" coloration. He is a mini rex.
Ella, a Dutch (and who also has a gray "otter" coloration), was also born in May 2014, but I didn't get her until recently. I found her in the free section on Craigslist and felt some odd compulsion to take her in, even after seeing and rejecting dozens of cute baby bunnies in the pet section. When I got her she was quite overweight and clumsy, and in insane "I-want-to-be-a-mommy" mode. She marked every surface she could with urine, was very musky, and sucked up any touching or attention she got. She'd lick me and circle like crazy if I tickled her sides! She has never punched or growled at me, despite her hormones. Very, very sweet girl.
Now Ella has lost some weight and is starting to get around to places in the cage that only Jasper could reach before. She is slowly realizing marking is useless, and seems to be receptive to me showing her where to "go." She's very happy with the house I've made her and loves Jasper (who is the best husband ever - she better appreciate him!) as well.
What can I say, I love my two bunny butts.
I was surprised to see her up on this level with Jasper today, go Ella!
