how many do you have? nonbreeding rats that just hang out as pets? i currently have 9 and thinking of bringing the group number down.. .to a more managable number. right now they are all living in a large martins (Rudd) cage together and there are a few rats that we have are simply not as friendly..one in fact has been biting my hubby lately and obviously thats a huge no-no in our house.. im thinking less rats, less to clean, more attention per rat. does that make me a mean owner to thin out a group of less friendly rats to give more attention to the good rats? i do have a great place for them to go.. not to be food
