My new fur baby nearly 6 weeks old. I have only had him for 2 days. I'm worried he is deaf. Nothing startled him. I googled it and did la heap of tests. He does wake-up when I open his door . But the dog barking and I pitched noises don't bother him. They said that kittens don't like the vaccum. So I tried that and he did shy away from it. But still unsure. Any help would be great
