Why has my kitten's sweet disposition changed?

Four months ago I got two kittens, a male and female, 2 months old. Both have been spayed and neutered and had their rabies shots. They were not related, but had been together throughout their stay at the Humane Society.

When we got home they were inseparable, always playing, eating, and sleeping together. The male, Andy, was twice as big as the female, Abigale.

Andy started to go outside in the daytime, but Abigale would not go out. Then Andy started staying out all night and was sleeping in the barn.

One night, Abigale did want to go out. About two hours later she was at the back door, sounding like she was screaming. She had also pooped next to the back door on the porch. This has happened three times since. Abigale seems scared to death because of him.

His whole sweet and playful disposition has changed. He looks at me like he doesn’t know who I am. I put food and water in the barn for him and he comes during the night and eats.

Can you tell me if cats have always done this? What should I do? Abigale is an inside cat, for sure. Thank you for any advice.
