I adopted Zeus a little over a year ago.
It took him 6 months to really feel comfortable here and about a full year for me to think he is absolutely comfortable. He still has a fear of me leaving him (except when I leave the house) and I doubt he'll over get over that.
He picked up his first toy about 7-8 months after we adopted him and now he will join in playing. Which is great! I'm going to give another 6 months or so before he'll bring a toy to us....fingers crossed!
The stink could be his food. Does his bite at himself a lot? What are you feeding him now?
