Without foster homes, we simply could not exist. While the responsibility of fostering a rabbit is real, TRR assumes all associated cost including veterinary care and food (unless families wish to contribute this themselves).
Please understand that if you apply to be a foster home, TRR will contact your references and  request a visit to your home. While we appreciate all the the help we can get, we can only consider serious, dedicated applicants. 
As a foster family, your duty is to keep your rabbit safe, happy and healthy, but also to help us assess their personality so they may be matched with just the right forever home.
There is no way to know when a rabbit will find his/her permanent place, so we ask that all applicants be willing to commit the time it takes.
