My Mother got my cat into a pretty annoying habit. While out of town, she let the cat drink from the bathroom sink faucet a few times and now the cat practically knocks you down if he thinks you are headed to the bathroom to turn on the faucet. He will even jump up and try to muscle his way to the sink while you are brushing your teeth. Lately, he has resorted to the toilet. I have tried the cat fountains, thinking it was the flow of the water he liked, but nothing seems to break him of this habit. This has been going on for a couple of years now and I'm out of ideas. HELP!!!!
