So what the hell causes it? Well I can only think it's to do with all the crap they start eating at this age. Leaves, cat shit, mud, grass, stones, hair and anything else they can find. No matter how careful you are, it happens. Because they had found their way through to the planted garden we had already banned them from the front garden.
The vet are going to provide us with some probiotics and we are to stick to fish and rice for some days now. (They stressed no chicken just white fish!) As long as they are eating, drinking and playing then there is no reason to panic ... apparently!
