i know many people say stay away from pet stores, but thatdoesnt mean you absolutley have to. I got my mini rex from a not soclean pet store, and he is fine! and actually after his first week, hewas already kissing me and begging to be petted. Pick a rabbit fromanywhere that you feel a connection with. and i actually got mineneutered last thursday, and for me it was only $35! and he isdeffinately starting to get less agressive. my parents werent sothrilled on getting him nuetered at first (because i always thought heshould) but my mom noticed how the pee smelled, and he took advantageof my stuff animal i let him live with. sooo she knew it was time. Imso glad i did, and its easy, just listen to what the vet tells youabout not feeding him before, and let him rest for a certain amount oftime, and you might want to ask them to clip his nails during thistime, and/or teach you to do it.
good luck!
