a Large dog/cat door (Mills River)

Due to Helene, our dog/cat door is completely ruined. It's located in our family room and it's just too cold in there now. We have to keep the door open during the day because that's how the dogs get out to go to the bathroom (we have an invisible fence). If anyone has an extra one or know where I can get one reasonably priced, please contact me. I'd really appreciate it! Thanks so much💕
