It could be an infection of mites, causing the hamster to scratch itself excessively and cause bald patches. Or it could just be a sign of age.
Yes, it could mean mites.
It could be a mutation
Could be embarrassment.
No, spider mites are not at all dangerous to humans. They do not bite humans either. The spider mites will not infest a home either.
if you call a dog's name or make its favorite sound and he/she doesn't react it could mean it has water in it's ear or has an ear infection. If you suspect this, you should take your dog to the vet.
A cat can pivot their ears 180 degrees to hear. Their hearing is far better than humans and even better than dogs. A cat's ear has 32 muscles and each ear can move independently of the other. They also use their ears to communicate. If a cats ears are flattened, he is feeling threatened. If they are flickering in multiple directions, there's probably a lot of sounds and he's trying to figure out what they are. If his ears are perked and facing in one direction, he's interested in what he is hearing from that direction.
More than likely if there is a bad odor coming from the ears it either has an ear infection of some sort or ear mites. Either will need a look/check by your vet to determine just what is wrong and to give you the appropriate medication. A cat's ears that are healthy should have little to no odor.....it's a sure sign something is wrong.
If it is a vigorous shake the it is trying to dislodge something such as a fly or dust. If it is a quivering type and the weather is cold then it is shivering and needs to have shelter and a blanket to warm up.
It doesn't necessarily mean anything. She could like that she received a "note" or she could be sharing it with her friends.
it depends what you mean by "scratch".if you mean scratch a back, then no. the first few times they do, but then it gets annoying.ifyou mean "other places",if you know what i mean,then yeeeees!
You probably mean dust mites.
