My 5 month old kitten has started randomly peeing outside the litter tray, she doesn't do it every time just now and again. Saturday night she peed on out bed and this morning on our sofa. She has peed on out sofa twice before in the last few weeks. There are two litter trays in our flat which get cleaned out daily and the litter changed throughout the week. Food and water are in a separate room. We have another kitten who is absolutely fine and a 2 year old cat. They all seem to get on with each other and play. They are all indoor cats. My husband is talking of getting rid of her because we have a baby on the way but that would break my heart!! Any advice please??
