Woke up this morning to the distinctive smell of cat spray in our sitting room.
Last night we decided to let girl cat sleep in there as the stove was on and it was going to be cold. Normally both cats stay in the kitchen and dining room overnight with access to the cat flap. Boy cat slept in his usual place.
We do occasionally have other cats trying to come in but the girl cat is very vocal about not letting other cats come in - if it had been an intruder cat we definitely would have heard her.
Could the snow have freaked her out and made her spray?
