all of my cats had litters of kittens inside the doggie door/dog house that my golden retriever stayed in and on occasion the kittens would latch onto mama dog as she became known. i don't know how normal it is or what to do about it, but that happened a lot at our house and we didn't really do anything about it, Ruger was big enough to fend for herself and didn't seem to have any troubles from it |
