My kitten has been really good with his litter box since I brought him home (I have had him for a little over a month), however he has peed 4 times outside his litter box for the past 2-3 days, and has pooped outside it once. He has peed in the same corner of the room (his box was only a metre away) 3 out of the 4 times and on a plastic bag the other time. I also came home to a piece of poo in the middle of the room a couple days ago. Otherwise he still uses the litter box. He has 2 litter boxes placed conveniently. How do I let him know that this is not acceptable? I've also noticed he flops onto his side a lot in the past 2 days, and prefers resting/sleeping on the hard floor rather than a soft bed. He is playful when I interact with him but I have given him a lot less attention due to commitments recently, is this a sign of boredom, or something health-related?
