Some pets are doing the weirdest things on repeat—and it’s not just for laughs.

If your dog zones out watching a laser dot that disappeared hours ago or your cat obsessively licks the bathtub faucet, you’re not alone. Pets have quirks that don’t show up in training books but are clearly wired into their little brains. These oddball habits aren’t just strange. Sometimes they’re rooted in instinct, stress, or leftover survival tricks. Some are harmless, others are warning signs. All of them make you look twice.
