Hi, a family member is looking to adopt a 6 year old cat from a local RSPCA charity. When she visited she was advised that the cat had a grade 2 heart murmur. She was a very placid quiet cat indoor cat which would suit them perfectly. They are a little concerned about the murmur and if they would be able to insure her. The vets have checked her out and everything else seems absolutely fine but this has concerned them. Does anyone have any experience or advice. Thanks
