I've been reading all sorts of websites regarding proper care. In every one of them it's been said that gerbils should be in pairs. That is all fine and dandy but this gerbil was with another gerbil and had to be separated because this one started attacking the other one.

Since I've got him, I've made an effort to visit and handle him once a day at least. My cat Raziel is almost always sitting next to the tank licking his lips. So it's not like he is alone all the time.

Do you think he will be ok as a solo gerbil?
