Hello. We got our daughter 2 14 week old male rats a week ago and could do with any tips on getting them used to us! They will approach our hands in the cage for treats but only one will let us handle him. We have had them out the cage every day for the last 4 days for free time (in the empty bath) but transport them carefully through in their Sputnik beds. They are curious and explore the tubes and boxes (and treats!) we put in for them. They are also responsive when in their cage and come running up to the front when we talk to them! My worry is that if we don't handle them enough, they will not tame as well in the long run? On the other hand, we don't want to stress them out by trying to handle when they are still nervy. Any suggestions or advice?
