We had a cat once. It was smart. It knew when it was dinner time. If he didn't hear the can opener, mom would sometimes leave fresh meat on the counter or table. When she left the kitchen, he would come out of nowhere and jump up to the counter or table and start chewing on it.
That's how he turned on the can opener. He had servants!
We have a Weimaraner who thinks we’re her servants. Give her a treat, like a Milk Bone, and she’ll just hold it in her mouth until somebody is settled in a chair. Then she comes up and drops the treat in your lap. What she wants is for us to hold the treat while she takes small nibbles off of it. Bizarre behavior...but we accommodate, LOL.
