I'm looking to soon be purchasing 2 RETF's. I've seen a pair for sale at PetCo but I'm not entirely comfortable or trusting of the animals they sell. Would you recommend me buying online or would you say the sad RETFs in the small glass inclosure with minimal climbing surfaces would be ok to go with. I almost feel as though I need to rescue them, but then I remember they are a chain and will just put some more in there. If you know of any or have had success with certain online stores, please let me know. I have never bought a live animal over the interwebs before. So all input or suggestions/concerns would be fantastic!
