It is normal for a bunny to pull their leg away when you try to touch it, but IF her foot is broken she would do that too. Rabbits are experts at hiding injury – it’s part of their prey instincts.
Have you noticed that she hops funny or is licking it more than normal? Is she leaning towards one side more than another? Is she eating okay? Is she grinding her teeth?
How long ago did this actually happen?
One thing about a foot injury is if it is broken, and it’s not reset soon, it may never be able to be reset. Do you have friends or family members that could help you out in this situation? I am thinking that if you have to save for gas money, you may have a problem with the vet bill for this too. Bunnies are not cheap patients.
I have a tip that may help those of us who are not financially prepared for emergencies. Get a credit card for just this kind of thing – emergencies only. Then get pet insurance. I use VPI. It’s about 11 bucks a month, but they will pay for about 70% of the bill (anything but parasitic diseases etc ) http://www.petinsurance.com That way, you can pay with the credit card, put the claim in for the insurance and a few weeks later when you get the payment from the insurance company, you can pay the credit card bill with it.
