I've had cats (one kitten) before, but this has never happened to me... I need help. I've had my two kittens for four weeks now, they're 12 weeks old. They knew what the litterbox was for right from the start, but up to this date they keep peeing everywhere else too. It's happening less frequently now but that's probably only because we've taken away opportunities. They pee on our cushions/pillows, on the sofa, our laundry, our bags, our dinner table (!!), and a few days ago Mila jumped on my legs when I was sitting on the sofa... just to pee on them.
They seem happy, not stressed, they play together all the time and they get a lot of attention from us. They have two litter boxes, one in the living room and one in the hallway - I've heard that three would be best but I wouldn't know where to put it. XD
We've removed a big sitting .. thing.., like a Fatbox so to speak, and all of our cushions/pillows from the sofa, so they can't pee on them anymore. We've got them stored away right now.
When we see them do it, we immediately pick them up and put them on the litterbox. We also spray their peed-on spots with a special spray that removes the scent, so they won't (or shouldn't) do it again. I'm out of ideas. Any tips?
