Help misfit the 3 footed bunny

Hi everyone! I'm raising money because my bunny needs her whole leg amputated! My boyfriend and I saved her from a horrible pet store. They told us that she was a normal bunny, even with her missing a foot. And she was crammed in with about 20 other bunnies in a small cage. We were told that the reason she had her foot amputated was because of a birth defect. She seems to be just like a normal bunny but I looked at her leg today and it was much worse then before. So we found the best bet we could in Houston and they told us that she should have had her whole leg ( up to the hip) amputated. They gave us the price of what it would be to to get it removed and they told us it would be around 1500 with the medication she will need after and everything. My boyfriend and I are only 18. Still in school and we don't make enough money nor do our parents to help our baby. I love this bunny more then anything and I just want her to be the best she can be. Even with out her leg. Any thing anyone could do to help would mean the world to my boyfriend and I. Thank you so much
