When I took him in again for his baby shots, the vet laughed... well not laughed, sort of did an odd half smile that cracked me up! Like "what a guy." We had him on solid food immediately.
Because it had been a while since I was a mother, I was sort of lucky that I had the flu for a few days. I put him on my bed with me and he slept in a little box with a shoebox of litter and explored while I was awake. He also bit the HECK out of me! It must have been separation anxiety or something, he was a nasty little thing and I was a chomped up mess.
I have been told to always play with toys, not hands, but he would bite in my sleep! I took him to the vet and when we fixed him, the vet suggested filing back his baby teeth! They would fall out eventually and perhaps if I didn't scream all the time, he would not get such joy!
