DCAT is 15. She hasn't eaten properly for a couple of weeks, probably last had a meal a week and half ago. She is drinking. We took her to Vets on Friday, who did lots of tests/checks - liver, kidneys, heart, teeth etc - all of which came back fine (Vet said test results were the best she had seen for a 15 year old cat!). Vet gave puss an injection which she said might stimulate her appetite, and said to come back in few days if no improvement.
There has been no change - still not eating. Other than looking very thin, she looks well: eyes clear, coat shiny etc & she's still sociable. Today when I came home there were some lumps of a tar like substance where she had been sleeping, they didn't really smell so I assume she had vomited them up.
I've booked her back into vet's tomorrow - but has anyone had similar or have any suggestions what might be going on with my lovely girl?
