Design problem- Mice and small rodents can get in the heater box to stop air flo

Thank you. I guess I will just have to live with it for a while and learn how to clean out the heater box by myself. I do keep D Con under the hood. I have less the 35000 miles on the car.

Thank you for your reply. I keep DCon under the hood. Don't want to kill the cat. Also the cat would probably become either coyote food or fox food. I will try putting peppermint oil in the heater to repel mice.
