I do like that you chose to use cats, and the gameplay was actually fun. I agree with Hiddenone that the camera angles gave me some VERY close calls, but I actually didn't mind it because that added to the challenge of getting through the maps. I liked how the tension between maps kept rising, as the maps seemed to get hazier/darker as you passed through each level and the music became more distorted. I wasn't necessarily scared, but I did feel more claustrophobic as I got deeper and deeper through the levels.
The only problem I had was that the jump lagged for me on occasion, but that's not necessarily anything you can control, and it DID allow me to test if a Mario Bros stomp could kill anything... which it didn't. :(
Overall, I had a lot of fun with this one. I feel like the biggest strength in this game is the atmosphere. You're not timed and the enemies don't follow you, but you're still feeling pressured to get out as soon as possible. Well done!
