Why does my kitten have mouth sores after we recently moved?

Pet's info: Cat | American Shorthair | Male | neutered | 6 months and 2 days old | 5 lbs

Hello, I own a four and a half month old orange tabby domestic short hair kitten. He is strictly an indoor cat and is fixed. He only eats Acana kitten food. Wr resently moved and like a week ago and I realized he is getting canker like sores in his mouth, nothing have changed in his behaviour and he is still eating but when I went to clean it he did not like that. What could it be.?

There are some viral infections in cars that can cause ulcerations on the tongue. A common one on cats is called calicivirus. This virus can be carried by very healthy cats and only cause a flare-up during times of stress, such as a big move. This virus cannot be transferred to humans or dogs, but is contagious amongst cats, especially younget ones (as older cats get continually vaccinated against this). If he is eating and otherwise acting fine, there is not much that can be done. However, if he stops eating/drinking or develops nasal or eye discharge, you should consider taking him in to your veterinarian.
