I now have 3 cats with this... My little Bing Bong ( as i lovingly call him) has been at the vets today for bloods. I think i knew this by his behaviour but im still sad and was hoping it wasn't this. Im actually quite devastated at the moment to think eventually 3 of my babies are going to come to a horrible end. I'm sorry if this sounds dramatic but thats how i feel right now and i have no one who really understands. He is also being tested for thyroid as well.
