When your cat was young, did you play with him/her with your hands? Did you let him/her bite you hands playfully? If so, that may be the reason. Here is an article that gives some info on it. Hope this helps.

my cat is a outdoor cat it will get more aggressive if outdoor if i were you i would keep it inside indoor or outdoor you decide
I don't think you should.. your cat could eat a poisonous spider and get hurt.
yes it can because if the cat is not a stray cat and it is your friends or something like that and it is outside it can become a indoor cat
Every time the cat gets close to your flowers, spray the cat with water.
Yes, they can. you just need to play with them and make them think the being inside is better them being out side.
your cat may have fleas

your cat may get aggressive because you ignore it or play with it too much. also, a cat may get aggressive is it has been around other aggressive cats or other animals such as dogs. you should try leaving it alone for a day and take it slow by only stroking it a little and talking softly to it. Also, if your cat is old they tend to get grouchy and grumpy. i hope this helped!
well if the cat is an indoor only cat they can live to about 20 years tops but if its a indoor outdoor or only outdoor cat then probably 10 or 15 years.
Nothing, then you have yourself an indoor cat.
Should be "forever". A safe cat is an indoor cat. Stays healthier and free from contracting diseases from other feral cats and loose cats.I have a 13 and 15 year old cat and they have been indoor cats. If you want them with you a long time. Enjoy them indoors.
Stress can cause a cat to be grumpy and aggressive towards people
