There are 2 cat videos tagged with cat-door.
After two days, Philo Cat finally warmed up to the idea of a "cat door." Some YouTube viewers pointed out that I was speaking to him in "English," and that was the problem--cat's can't be expected to respond to "English." Others pointed out that I should have called it a cat-"flap," not a "door." This technicality, they said, confused the poor feline. Still others said the problem was the vertical filming! Turns out they were all right! As soon I began speaking to Philo in ancient Sanskrit, referencing the "cat flap" and filming horizontally, BAM! It was like magic, right through he went! :)
