Oml, okay, this is a longish story so be patient

Last year, one of my cats had kittens, 4 to be exact, one was named George, the other, Ursula they were tiger cats. Ursula was shaking when she first started moving around, so when she was a month old, we took her to the vet. (we waited until it was warmer outside since she was only a kitten) There, she was diagnosed with Parkinsons disease. (where you shake inhumanely or in Ursulas case unlike an average feline) At first she belonged to me, but that changed soon when my mom began working from home, she became my mom's instantly. After that, my dad felt bad for me not being able to have a kitten, so when our other cat got preggo he let me keep one of the kittens, which is my cat, Mars. Mars is a black cat with one light brown eye and one dark brown eye. When he was first born I thought he was a girl, and at the time, one of his eyes were a pretty emerald green color while the other was still a dark brown, so i decided to name him emerald. When I found out he was a guy, I tried to pick a name that started with em or m because his nickname was Em. I don't remember exactly how it happened but I think that my little sister was talking about how one of his eyes looked like chocolate, then she asked my mom what her favorite candy was, my mom said a mars bar and then, BOOM! Thats how he got his name. Anyways, back to the story earlier I found out that he was trying to fuck Ursula, and my dad told me that the last thing he wanted was for Ursula to get pregnant first of all, because of her shaking, second, because of the weather. So now i've got to keep my cat in my room all day, even when i'm at school. Fml.
