I bought Troy some Dreamies as a comforter when his brother died recently. Neither cat had had treats for over a year because Barnaby who had crystals in his urine was not to have treats so it was easier for neither of them to have any. Both times I have given Troy Dreamies there has been massive, and I mean massive, piles of sick everywhere. I haven't given them to him for a good few weeks and no sick. Could it be the Dreamies or not or should I try some again and be prepared?
