They are curious.
The cat's curious.
Not many cats do but i think its to get your sent.
It means there is something about your ear or the side of your head just there that smells interesting. Cats don't do much that has deeper meanings; they are very immediate creatures.
The plural of sniff is sniffs.
to get the males sent.
It can mean several things; for example, the cat may have been hungry, and is looking for food.
Yes they can! My dog always sniffs and even eats our cats poo but make sure he doesnt!
Having a black cat on your shoulder can mean a couple of things. One meaning is that it is good luck.
This could mean two things. 1) Your cat could have fleas 2) Your cat could be stressed Either way, consult your vet about this.
well, cats are mean for many reasons. if they are not loved, fed, or cared properly. To help your cat with being nice, do these things and if this doesn't work, a cat obedience school should get your cat back on the nice list. :)
When a cat swishes its tail back and forth quickly, that generally means that it is agrivated. The best idea would be to stay away from the cat when it is like this, or you may risk being scratched or bitten.
I don't really understand what you mean, but catnip makes a cat hyper. I don't think sour things will make a cat hyper.
