Our kittens are about 18 weeks old and after a few accidents when then moved in, they have been really good with using the litter tray for poo and wee's. But one is using a couple of areas in the house for wee's and I'm struggling with how to deter him from doing this. I can't tell if it's one or both of them as they won't keep a collar on at the moment and looks so similar.
Any suggestions or advice?
Also any advice for what to use to neutralise the smell as we can't open any windows at the moment due to them not going yet, so my husband is not pleased at having a stinky house 😢
