My 8 month old British Shorthair was rushed into emergency pet aid hospital early hours Sunday morning as he was gasping for breath, they found fluid on his lungs and chest and he was turning blue. It was touch and go for a while but he managed to pull through and I took him home yesterday. The vet has told me he has a serious heart murmur and they have put him on 2 pills a day for the rest of his life basically. I am due to go back in a few days or a check up as they dont know if he will take to the medication yet. I am very very upset about this, he was a healthy kitten and 2 weeks ago he got neutered. At the pre-op check up I asked the vet if he could check his heart as I started to notice him getting out of breath when we played in the house. The vet checked it for all of 4 seconds and told me he was ok. Since this happened at the weekend I have been told it was probably the anesthetic that triggered the attack. He is an indoor kitty and I blame myself for getting him neutered AND the vet that supposedly checked his heart! I dont really know much about heart murmurs and the vets where he stayed were not very helpful on the subject, just wondered if anyone had gone through something similar?
