Yes all the supplies probably aren't the right supplies. For exampel I bet that 'teddy bear hamster' actually called a syrian hamster is in a tiny crittertrail/habitrail cage when it deserves something like a 20 gallon long or 2-3 habitrail/crittertrail cages. Just be prepared to buy new supplies and such. And becareful is any of them was in improper care then they may be sick/injured and need vet care.

I think as long as you have the time and money then you are alright. Many of my friends think I have too many pets and they believe that I spoil them when although they are fairlyspoiled it is mostly just me giving them the proper care they deserve. C=
