When I was a kid my pet box turtle started doing this thing where he lift one foreleg and Stretch his head straight up, mouth open, waiting for me to hand feed the spoiled little shit lol. I never figured out when, why, or how it started, though it was only with worms. I still miss the little guy, 3ish decades later.
Point is, sure it may be somewhere on the silly to obnoxious spectrum, but pets generally don’t live as long as we do. I say just adapt to their quirks and enjoy the ride. If nothing else, it’ll make for find memories and a funny story later.
