I'm so sorry to hear that you cat died...I know that loss. Take her to your vet or local humane society. They can dispose of the cat for you. I didn't know it was illegal to bury a pet...is that a Missouri thing or a county thing? Interesting. Anyway, about your grandma...if she is living with you or you with her, you need to explain to her that your health problems were because of the cat she owned. If she is against a dog, then explain that a dog can be more loving than a cat. If she still is against it and wants a cat, you may have to play hard ball and tell her that you will have to put her in an assisted living home if she is insistant on living with a cat or two. You need to make it clear that your health depends on not having a cat and so does her great-grandchildren. And then you may have to tell her that if the cats are still around when she dies that you will have them put down because you will not care for something that is causing you health problems. I know it sounds harsh, but she sounds as if she is slightly stubborn herself. I don't know if this is helpful, but I do pray that your situation works out and you are able to keep caring for your grandma. Good luck and God Bless.
