My son has 3 cats. He recently had a huge life change- his wife left him and the cats must be able to pick up on his stress. After she was gone for about 4 weeks he became very depressed. One of the cats started pooping on the floor. The other started with the runs and would go in the box but finish on the floor. We went to visit him and they didn't seem to do it too much but I did notice one had the runs. Took the one we thought had the runs to the vet and they checked his anal glands. Said all was good. Took the cat home, left and came back .. One of them pooped runs right by the water dish. We thought if we put puppy training pads down it may help protect the carpet.... Well now they think they can pee on them. I don't know what to tell him to do anymore. He is stressing even more now. Hates the cats which used to be one of the most important things in his life.
