I have to tell you guys a secret about my cat moon.
A few years ago, his personality changed. Instead of being my sweet little kitty, he would scratch and bite me whenever I approached him. He even goes into hiding for two weeks at a time, often whenever someone comes over to my house. Moon hates other cats. A few years ago he saw another cat and attacked my dad for some reason. He launched himself into my dad and bit him and scratched him so much that my dad had to use a broom to defend himself. I don't know why Moon's personality changed.
Luckily, my other cat Licks is still very cute and she has not changed.
