Electromagnetic Pet Door by Smarthome for a greater control on your pets
What better solution could be there then a pet door which you can give directions to? No, you don't need to see an ENT specialist. Other animals that used to pass through that 5.5" x 5.75" opening will now be restricted. No Entry! That's what I call it. Now, you can protect your home from stray animals and rodents, still allowing your pets to pass through whenever you want to.

This Electromagnetic Pet Door by Smarthome has a weatherproof flap, which unlocks only when it senses a magnetic collar key of your pet. Other animals will simply find it locked. However, the good part is that it has four settings overall and you can fix them up. These are 2-way, entry only, exit only and locked. So, you can even punish your pets for their misbehavior sometimes. It is powered by a 9V battery that doesn't come with the kit. The kit comprises of a pet door and two magnetic keys. And if your keys get lost, don't worry, you can purchase an extra for $10.
