Why would you need an outdoor cat house?
If your cat is anything like mine, they decide that they want to go outside minutes before you want to go to bed. How many times have you stood there late a night shouting for your cat to come home so you can lock the house up and take your weary body off to bed? You stand there waiting for your much loved cat to come home because you don’t want to leave them out all night in the cold and rain. I know from personal experience it’s hard to fall asleep when you’re aware that your cat is outside in the rain and cold while your snuggled up in bed, especially in the winter. How many time do you get up and go to the back door to call them in? Eventually you’ll reluctantly give up and hope your cat is ok and has found somewhere warm and safe for the night.
