Ok so my mom's cat has been recently diagnosed with a stomach lymphoma which means she has just weeks to live. We've got her on meds and she seems fine for the time being but its hard knowing that she's pretty much living on borrowed time. What we haven't done however, is inform my older sister about the cat as she was the one who had brought her home initially and before she married and moved out, this had been her more her cat than anyone else's. She's coming to visit this week but we aren't sure how to tell her. Is it best to tell her now? Or after the cat is gone where she can't throw all her savings into expensive treatments which might be more traumatic for the cat? This is going to destroy her either way, I just don't know how to explain this to her without having her go apeshit at us and make stupid accusations about how we should do anything and everything to save her. We've gone with the option that's the least traumatic for the cat (because this way she can stay at home and not go to the vet's every week since she hates it there so much) but she ain't gonna see it that way.

- Honestly, if it was my cat, I would want to know asap, so that I was able to spend time with it and let its last few weeks be full of love. If she is the one who adopted the cat, and loved it, she really deserves to know. I would just explain the situation to her as calmly as possible, and if she wants to put money into treatments that may or may not help, that's sort of her choice if it's her cat? If the family has decided that they don't want to go through with more treatments and she doesn't really have a lot of say in it, just explain to her that it's what you guys think is best for the cat, because you don't want it to have to suffer through difficult treatments.

Also, you never know with animals. They're pretty amazing. There is a cat who's family I follow on Facebook, who has malignant lymphoma, who is going through treatment and is doing pretty well, even though they through that he wold have passed away weeks ago.
