Why is my 3-month-old kitten so aggressive and destructive?

Updated On September 23rd, 2025

Seems the be overly aggressive lately. Scratching, biting, climbing up my legs, fake crying and attacking when I investigate the crying, sulking away even when offered treats, bouncing off the walls. She has a cat tree, tons of various toys, and feed well, but still destroying my apt while I'm at work. Agression seems excessive from normal 3 month behavior from what I read.

Sudden aggression and behavioral changes in cats can indicate pain or illness, so if you haven't already, a veterinary check up is best. If your cat checks out healthy, it may be there is a lot of stress causing your cat's behavioral issues. Making sure she has her own access to food, water, toys, treats, hiding spots etc from other pets or people is best. She is also still very young, and may just have a lot of energy/is still learning what appropriate behavior is. Ignoring bad behavior, increasing play and activity times, and rewarding calm, quiet behavior is best to teach her the right way to interact and to get out that excess energy. If the behavior continues even with this, speaking with a veterinary behaviorist is the best next step.
