I have had Mrs moo about a week now but only had the rex girls 4 or 5 days now. Mrs moo was affectionate from the first few seconds of meeting her but the rex's are coming round now. At first when mrs moo was pushing and sniffing at my had I wondered if she would nip but she's been licking me and I just sat with my hand in their cage today and all 3 were licking my hand. Is this affection, washing or just checking for food?
