My neighbour lets my cats in and feeds them even though they are mine. I have explained that they cant have wet/meat food as they are on a dry food diet and wet food gives them upset tummys.
My little girl cat his just messed all over my table (sorry TMI) and i know its because she feeds them.
Yes they love wet food, we do give them treats, but its driving me mad. Im also struggling to get them home some days
