Why does my Ragdoll wait by the door when I come home?

Probably thinks you're bringing in the grocery bags with the good stuff. My cat does the same, and I'm pretty sure he's just checking if I remembered the salmon. Cats aren't exactly known for their loyalty like dogs, so don't assume it's pure affection - it's more likely he's learned that your arrival predicts food, treats, or a warm lap. Unless you've trained him to associate that door with something positive, he's just waiting for his next meal ticket.

You're overthinking it. He's not waiting for you out of some deep emotional attachment - he's waiting because your arrival breaks up the boring routine of his day. Ragdolls are smart enough to know that door opening means a change in the environment, maybe a new smell from outside, a chance to investigate your shoes, or the possibility you'll sit down and give him attention. It's just pattern recognition, not a romantic gesture. Keep it simple.

Your cat has learned a simple cause-and-effect pattern: door opens, you appear, routine changes. It's not romantic attachment, it's behavioral conditioning - he knows your arrival signals a shift in his environment, like feeding time, playtime, or just someone to watch. Ragdolls are observant, and that spot by the door offers a clear view of the only event that reliably breaks up their boring day. Don't read too much into it unless he also brings you a toy, then maybe he's just bored and you're the entertainment.
