yes, you really need to spay your rabbit. another rabbit may make it worse. not trying to be a hypocrit, i have bred two litters. it is a fun expirence (sp?) but they are hard to sell and no more bunnies in this world is needed. I do have hollond lop CROSS bunnies if you want one. please dont chew me out because there crosses, whats done is done and i have learned my lesson. If you would like a bunny of mine you can have one. but two things-
1. you have to be within two hours of me. it is too much stress for a bunny to travel across the country.
2. You have to nueter the bunny if you want one. no breeding my rabbits!

good luck!
