Hi lost my cat aged 16 three years ago anyway got a kitten 5 months ago had him neutered when old enough but what I can't stand is his smell as soon as he uses the litter tray the whole house knows about it , is it normal ? I've never know a cat smell so much he's been like this from day one , I took a sample to vets that was all ok , I've just took on another kitten feral and he isn't done yet as not old enough but he doesn't smell help ?
