Your Boyd sounds like our cat who departed us last summer, Crick. (The other one still with us is named Watson, so guess what famous duo they were named after.)
Anyway, Crick was the one we had to watch out for. He very nearly knew how to open doors with regular knobs, but if you had the lever types, he had those figured out!
He escaped so many times, a very fast mover. He would paw at a door until it would open just a smitch, then he would scoot right through and go find a hiding place. He was my sweet, sneaky, little monster. Miss that little boy.
Fortunately, we still have his partner in crime with us. Watson is a good boy, too. Not nearly as mischievous as Crick was, but he has his own ways. He sleeps with us every night, sometimes on my head. He reaches his paw out and pats my hair. Funny little guy. 😻
“He reaches his paw out and pats my hair.”
Boyd does that to me, too!
Both Boyd and Eva know how to get into the lower cabinets in the kitchen. I thought about baby-proofing them, but it keeps them entertained when they are stuck indoors - which usually starts about now. Ugh!
