Bert has taken Holly de Cat to the vet after I secured an emergency appointment. We think one of the dogs has hurt her. There is nothing obvious on the outside but she vomited blood.
Update: The vet's opinion is that Holly has not been hurt. She thinks she has a stomach infection. She has received an injection, has been given medication and is to be kept hydrated. If she does not improve in the next 24 hours we are to bring her back.
