I wanted a FIV cat when we were looking, as it was going to be an indoor cat. Went to a shelter and wanted to take every one of them home. Yeah pathetic, I know. In my defence each cat was so lovely and spent time with each one as I wanted to be sure as I wanted to be a forever home.
Was told the FIV cats make excellent indoor cats, no idea how true it is. Has your cat had the FIV vaccine. Would that help?
Well done for look after the furball.
