One of them sadly passed away recently, so we got a 5 month old kitten as a companion for our older cat.
She's been with us three weeks and is getting on well with the older cat and our dog by now. They all play and sleep together etc.
The problem is that she pees all over the place, and it isn't just accidents, it is deliberate peeing on the couches, the beds, the dog beds, just now she squatted on a pile of laundry I had on the couch for ironing and peed on there. She also goes in the laundry room and if there is any laundry on there waiting to be washed, she completely soaks it. I know she can use the litterbox, as she has never pooped anywhere but there, but don't understand what the peeing is about. We hardly ever catch her at it, and when I just saw her on the couch I rushed over to grqab her and put her in the litter bin, but she ran away and I had to chase her around the house in order to do that.
There is a litterbox upstairs, which is her's entirely, and there is also a bigger one downstairs that is also for the other cat.
Any ideas on how to deal with this? I am really tired of the constant laundry and always washing comforters, dog beds and the mattresses, which already have protective covers on them.
