We think our kitten is deaf
He doesn't react to loud noises like clapping or whistling, even when he's awake. But sometimes it seems like he does react to noise, like I tested out the vacuum and he jumped at the sudden noise (could've been vibration startling him?) we're taking him to the vet next week to start on his vaccines and we'll ask them about it then, but we're just kinda confused. Like is he or is he not?
