I have seven cats, but only cause two of them had 2 babies a piece- so I ended up with 4 kittens. One of the momma cats belongs to my 16 year old little sister who doesn't have a job, doesn't pay for any of the cats, and hardly cleans up after them. The momma cats name is zoie, she's 8 years old, and she isn't fixed, we just got her last year and I haven't had the time or the money up until recently to get it done, but now all of a sudden, my sister doesn't want to get her fixed just in case if she needs to foster a kitten in the future. We just got into a fight because I'm adamant on getting her fixed, not only to NOT increase the overwhelming cat population, but also to help with her overall physical health. It can lead to a higher risk of cancers, physical stress on her body, and a bunch of other issues- but my sister is throwing a huge tantrum because I'm worrying about her health. I'm so beyond frustrated. I don't know what to do but my cats health comes before some dumb reason.
