I once seen a pregnant cat sleeping and laying down in that position. A golden retriever puppy came over and started lapping up milk. The mom looked up like “Whaaa??? You’re not my…oh, whatever. Go ahead.”
The cat ended up raising that puppy. Eventually that puppy grew to be a full sized young dog, but the cat didn’t care. She was still mama cat, and wouldn’t hesitate to cat slap that dog if she felt he was out of line. Despite being 10X bigger.
I miss that cat. She would love you, but she took no shit either.
