Hi, i am looking to getting 2 new house buns. i have fallen in love with two rescue buns a lady, one years old and a fella who is 5-6 years old. the boy has a bad eye and is getting it seen too soon and being neutured at the same time. hopefully the rescue can bond them for me. i am a little concerned though as i will not be able to get the boy insured. i have only had one experience of a vet visit for not the norm ie. jabs etc. and it was an emergency vets. what sort of problems do older rabbits encounter and are the vet bills very expensive?
