Responding to a post almost a year old about animals raising odd "children". When I was young my neighbor had a cat that had newborn kittens get run over. She was trying to bottle feed them but not much success. She only had two left when I found out. I suggested that we try to see if my dog which had just had puppies would take them. I took the two kittens and put them in a box with the puppies separate from the momma for about an hour. When I put them back with her she started nuzzling them back around her, including the kittens. One of the kittens never nursed but the other one lived about five years, two of which I think he thought he was a dog. He even tried to bark, made a noise as close to a bark as a cat could make. Definitely not a normal cat sound. He would even go squirrel hunting when I was training the pups, He was much better at climbing the tree than the pups. Sometimes even ran the squirrel out of the tree.
I hate sad stories about animals.
