My cats are both 6 months old and about 3 days ago one of them woke up in the night with diarrhoea and was sick - this happened a few times in the space of a few hours. He then went to sleep and woke up fine, eating and playing but still some diarrhoea. A couple days later the other cat has now started to do the same (sickness and diarrhoea). But both are absolutely fine in themselves, eating, drinking, playing and going to the toilet normally. I think it’s just worms but does anyone have any other idea or any recommendations on worming stuff?
