I have 2 cats, both 14 years old. One of them seems to be incontinent. Woke up yesterday to find a pop on the sofa, found little pops around the house about once a week for a few months. Quite unusual, never done this before. So my question is firstly how do I identify which one it is? And what treatment can I get? My husband is freaking out about hygiene, we have a 9 year old and a 4 year old. Thanks so much.
