Need advice!
So today I realised that the cage to my pet rats was open. To make it even worse, the person that was there (I was out of city) left the garden door open. I've been able to find one, not the other. There's a new burrow in the garden, so I'm really hoping she's in there! What else can do? I've left all sorts out there for her. I can't hear her in there. I'm worried for my other rat as they have bonded very well and she seems pretty sad without her sister. I don't know what to do?
