Just that. Was in bed watching a dvd, when I noticed my spayed female 3 year old cat was squatting instead of sitting. Though nooo she wouldn't be... But she was! Peeing right beside me. I've had her for two years and she's never done anything like this before. We have a dog too, but have had dog for a year so don't think it could be a jealousy thing.
Reading online they often do this when they want you to know something is wrong. Do I need to take her to the vet, or could there be a behavioural reason? know will end up taking cat to vet anyway but an opinion in meantime would be welcome
