One of my cats (Pixel) has recently taken to urinating in odd places like on my bed, the sofa, clothes etc. She's nearly 11 months old now and before this has been perfectly happy going outside. It's only in obvius places rather than off in corners etc. so I don't think it's an issue with going out. She's perfectly healthy otherwise, eating and drinking normally, bright eyes, glossy coat and all that. There is a slight chance she might be pregnant though. Has anyone else had an experience like this or do you have any ideas what it might be? I thought she might be a bit stressed and trying to get my attention but I'm at a bit of a loss
