Safety Tips For Outdoor Cat Doors
If you’re putting in a cat door that leads outside, make sure you get one made with durable, well-insulated, draft-proof, and weather-proof materials, as well as a secure lock to protect your home.
If you’re worried about strays and predators, consider one with selective/microchip entry. For your cat’s safety, you should also make sure their microchip info is accurate and that they’re up to date with vaccinations and parasite protection before letting them roam free!
