It's so very hard to see someone you love so much suffering and so many feel one's kitty is "just a pet." None of us here do. I went through a tough time when my sweet prince Nicky seemingly went from healthy to severely ill in 2 days and despite the best medical attention nothing could be done except the right thing for my boy but a very hard decision for me. I don't know you but your devotion to and love for your kitties comes across. Take good care.
