The vet told me basically what i thought, heart, can expect this. Since this morning though, she is now still coughing and vomiting the foamy stuff but the last few times there is blood in it which im worried about. Have phoned my vet again to speak to the senior vet to ask him his opioion, waiting to hear back from him . I never experienced this with Sam so am a bit worried. Also with Sam he never went of his food but with Bonnie she can eat for a couple of day really well then she wont eat a thing.
