My 3 month old kitten, Maya, has been showing some strange behavior lately. Every once in a while, I will take her to my friend's house (where Mayas uncle Simba lives) to play. The cats get along great but play a but rough, which is to be expected. However, lately I've noticed that for a few days after she's been ovee she will be aggressive. For example, today her and my five year old, felix, were snuggling on the bed. Then out of nowhere, Maya attacked her, and not in a playful way. I sprayed her and she jumped and attacked me. She drew blood on both Felix and I. This is the second time this has happened but it seems like a few days later, she will be back to normal. What is happening?!
