Ellie passed some blood on Friday so we took her straight to the vets - she is fine in herself, very lively, playful and affectionate. She is four years old, has always been quite slim but the vet said she has lost some weight since last year. She hasn't passed any blood since and I managed to get a sample late today (why do they never go when you want them to !) for tests. In the meantime she is on Hills i/d which thankfully she is enjoying and some paste twice a day which isn't so popular. Am just praying it isn't anything serious - any advice please ? The vet said it could be one of many things.
