Biobreed has released their beta version bunny and it's free.
There are 5 females and 5 males in the beta folder. I'm letting only 3 out because I need the space. 1 male and 2 females.
You can also hold them. Just take them back into inventory and add. You'll probably need to edit a bit like I've done.
Before birthing, the sleeping bunnies come in cute baskets. Pink blankets for girls and blue blankets for boys. Once the beta is over the bunnies will disappear. At the moment you don't have to pay to feed them so now is the time to have fun with these adorable little hoppers and not worry about your linden budget. Just worry if you have enough prims! Each bunny is 12 prims.
You can get your bunnies at the Biobreed Mainstore here. You'll also need to wear the group tag to get the bunnies. Group is free.
