I wouldn’t say mean (though others have).. He’s just perpetually anxious and overly defensive at times. Grumpy maybe. The dogs won’t go near him and the vet gives me a “chill pill” to be administered before each visit. I was referring more, though, to the way he patrols the woods behind my house. He learned to use the doggie door and spends nearly all his time in the warmer months outside pretending to be a jaguar in his little woodland jungle. He can also be really sweet and loving at times, but only really with me. He’s laying on my chest now, purring in my face. 😊
