I own two doe rats that i love to spoil. I met someone a few weeks ago that also had some rats, and we began talking. She said she let her rats outside ( in a controlled setting ) to play in the grass and such. Well Ive know of people that let their ferrets play outside, but what about rats? My first thought was the bugs and substances getting into their systems, so I didnt think it was healthy. Is it ok? Any and all views are appriciated!
