Hello friends, I am new here. Just got back from the vet with my 13 year old Maincoone She had lost 3 lbs in 8 months, hair looked bad and throwing up frequently. He did a complete blood panel, but seems to feel it is a thryoid tumor. Everything I have read has made me feel sad. Anyone had any experience with this? Thanks and looking forward to this forum. In addition to my Maincoon (Kitty) I have a Manx, (Stubby), 2 Cairns (scruffy and Sparky) and manage feral cat colony that I love very much.
