I havent been able to find the right cage and I wanted to know if the bars on this cage were too big :D

The only thing I would be concern about is the spacing between the bars and how big your ratty is. Im sure that cage would be just fine with a fully grown rat but not for a baby cuz they would be able to slip through. My cage has one inch spacings, but my two boys are pretty big.

I've seen those at pet stores - should be fine except for really small baby's. Frankly though, if you have any abilities with tools you should be able to construct a much nicer cage for cheaper.

The bars on the cage i bought for my rats when i first got them had widely spaced bars so i just put chicken wire around the cage ontil they are big enough not to slip through the bars.

if they can put their head and their are going to follow
