Dogs Need Outdoor Access—Cat Must Stay In. What Door Solutions Work?

Hello! I’m looking for advice on dog door solutions that will allow my dogs to go outside freely while still keeping our indoor cat safely inside. The cat never goes outdoors, but our two dogs need regular access to the backyard for bathroom breaks.

Ideally, I’m hoping to find an affordable electric dog door insert—or something similar—that gives the dogs access without letting the cat slip out. If anyone has experience with this setup or recommendations for cost-effective products that work well for dogs, I’d really appreciate the help.

Thanks
