This might be more suited as a MPSIMS thread but I’ll started it here in case there is an actual answer.
Own a cat. Male. Half Siamese, half American Shorthair. Fixed. Had him since he was a kitten. He’s 16 years old yet very spry and active.
Own a dog. Male. Pure bred Pug. Had him since he was a pup. He’s 7 years old. Fixed.
For the first 6 years of the dogs life the cat hated him. Even though the dog wasn’t aggressive towards the cat, it was obvious the cat hated him. Wouldn’t go near him, ran out of the room when the dog came in, occasionally hissed at him.
Over the last 3 months or so this has changed dramatically. It’s at the point that the cat is always cuddling that dog. Walks right up to him, wraps his paws around him, nudges his head into him, grooms him with his tongue, and purrs so loud you can hear it across the room. It’s now obvious that the cat absolutely loves that dog!
My wife thinks the dog penetrated him and now the cat’s his bitch. But that’s too weird for me to want to think about. I can only put it down as strange ass cat behavior. We’ll never figure it out. Is this just a case of “if you can’t beat 'em, join 'em?”
