There is no such thing as a cat over licking. If a cat licks itself a lot the cat can be in a lot of distress, have a skin parasite, or is just getting dirty a lot. I would check in with a vet though to be sure it is not a parasite or anxiety.
After your cat stop growing!
your cat will stop growning when she/he reaches adulthood (1 and a half) or if your cat keeps growning ask your vet
Why feed a cat? To stop it annoying you.
A cat will stop lactating when she is no longer nursing her kittens. A cat will know when to stop her kittens from nursing when she is ready.
Stop giving it treats.If the treats are in a closed cabinet, the cat won't be able to have any unless you give it some. When you want it to stop eating them, lock them up where the cat can't get to them.
Give it a bath - using cat shampoo.
You can spray some water on the cat.
