We have two and the other seems fine but the smell from the first is unbearable. He is ultra affectionate but we can't have him in the same room as us at the moment since the smell is extraordinarily bad and constant and also lingers for ages. Its literally making the whole house smell.
They have mainly dry food out with water but have a tray of felix wet kitten food each every day. Am I giving them too much dry food or is it likely to be something else?
