My kitten I adopted is around 8-9 months old and she is just a ball of energy for about 70% of the day, I think its hilarious but often times it can be frustrating when she wont let me do anything because she wants to play with me every 15 minutes or so. I know most cats seem to slow down, chill out and sleep more sometime when they are older but how much older until she will be more of an adult behaved cat?
