Hello!
Cats are curious and unpredictable creatures! Different typed of cats do different types of things. I am not sure what other cats do, however my cat enjoys to bite it's own tail. I suppose this is out of curiosity, or perhaps it's crazy. My cat also likes to bite at my hair. Perhaps, it likes the flavor of hair gel? My cat also eats my dogs food as well as smacks the dogs, which I think is hilarious. It also goes crazy when it's under a blanket. Lastly, my cat tries to eat her own leg when I give it catnip. (Yes, her own leg!) Those are just a few of the many strange things my cat does that I have observed of the time of having it in my possession.
I hope this helped!
I am, yours most sincerely,
