She must be devistated.All her cats are so beautiful and content looking.
My mom's orange cat was sick and my mom was sick and she couldn't give her orangie meds so me and mike took him at 15 years old.He lived happy w/us until his thyroid and liver finally gave out.He seemewd very relaxed w/us even in the first few days.Because he knew me.Remembered me.
I hope she gets to keep them but if not,her cat will do fine moving at an old age with you,since Fred knows your a family member I hope your sister gets better.Prayers on the way.
