There are days he is soooo gentle and even will groom my face, hands etc. Other days he is either "Cybil" or Dr Jekyle and Mr Hyde.
Yip got me a couple like that. Sometimes it's something I've done, others it's a cage mate,they may have been comfy and not wanted to be disturb at that time, or their just not in the mood.
Last week I caught a hold of a tail that slipped though. I must have tugged the fur loose, as next day the top inch was cleaned off.
He will not jump out on my hands now to get out for his run, I have to coax and beg, the end up giving him and empty bath, and then letting him on the floor.
Funny things is, if I go down in the day time and open his door, and I just did, out he jumps. He knows full well it's not run time, I'm only going to love him up and put him back.
Try it tonight at run time and he barks and grumbles and just will not come out to me, cause he knows I have to catch him again. His cage is just out side the room door, because that's where he wants it.
If I even put him just inside the door, and go down during the day, he barks and barks as soon as he See's me.
Put him back outside the door and he's an little sweetheart.
Listen closely and they will tell you what's wrong, or what they want.
