We found an abandoned kitten on the lake in the backyard. We've had her for a little over a month, she's about 9 weeks now. She was to young to be away from her mother and had been out for what looked like a week. My daughter takes care of her and lately she's started kneading and suckling on her blankets. I noticed she didn't do it as much while my daughter was gone for a week. Now she's back though the kitten has almost been doing it non stop. Is it something I should be concerned about?
One of our cats which died at the age of 17, was doing it through his whole life. So not to worry. He was also taken away from his mother when he was very young (the mother didn't want him) and was fed by my wife using a syringe drop by drop for the first couple of days.
This kneading behavior of mothers belly normally makes the milk flow, so it is a kind of childhood behavior and maybe for kittens taken away from the mother early, it doesn't stop when the cat gets older.
