I have three cats, two of them are 2.5 years old and one of them is 1.5 years old. Hermes, the 1.5 year old keeps peeing inside my laundry basket. He is very good about doing both number one and number two in the liter box, but he has pee'd inside my laundry basket about four times already over the past two weeks. He does not excrete anywhere else. Just the liter box and my laundry basket. He is the most attention demanding of my three cats, and I give him lots of love and attention. He is generally a pretty happy cat (all of my cats are). I have no idea why he insists on being inside my laundry basket. Any advice on how I can get him to stop?
