hello there, my names rachelle and i have had a gambian pouched rat for about 3 months now, Frodo. he's 18months old and he's never been handled and the last owners couldn't cope with him since he sent his girl friend to hospital. he's very grumpy and i was woundering if anyone had any tips at all, i get him out nearly everyday and i have just got to the stage where i can stroke him, i know he should come out and love to be with humans i just feel so sad, can anyone please give me some advice thanks.
