Okay so I need to rant. My dad whom I live with temporarily.. has three dogs, if they do anything wrong he is very rough with disciplining them.. it always make me super uncomfortable. Anyways, I was sitting in the bath relaxing and overheard him and my uncle talking about my kitten. They had just made dinner and my dad said "I'm going to put this in the microwave because I'd really hate for that cat too die tonight." Yes I said DIE! Keep in mind my kittens momma was just hit by a car and killed not even a month ago.. I'm so livid but can't say anything because it's "his house, his rules." If he EVER so much as hits my cat I'm going to probably lose it though and call the cops. I can't lose my kitten, I'm still so heartbroken over losing his momma. Help!
