Hi all, I have just become a mummy to my new addition t the house, Charlie, the 1yo border collie. I was wondering if anyone has some advice on introducing Charlie to Peanut and Butter? He has sniffed the cage, but backs away from them when they go near, and cleaning them out today was rather stressful for Charlie, I did get Peanut, my friendliest rattie, out for Charlie to sniff, but this was only brief as I wasn't sure how either would react! Any advice my lovely rattie friends???
