Eureka!Box: Internal cat door
Pet lovers, how many times a day do you have to get up to let the cat out of your living, bed or other room?
Cat doors are often fitted to doors that open to the great outdoors, but not to internal doors.
Funny the way some inventions only take a great idea so far.
Fight back club: Go invent one, but make it quiet and aesthetically purrleasing. 😉
