De you have a Lion?

I see the kitties are getting their flight simulator training hours in.👍

Now why can't these so-called engineers make something this simple on a smaller scale? I have now been researching self-cleaning litter boxes for days, and this is the best one.

10 pounds of litter just sitting in that bag stinking up the room? I’ll take litter on the floor any day.

Cat: well trained hoooman....

I thought my Litter Robot was big. Prob cost less than this monster.

I enjoy the concept and the design , but I think it's a little big and has a few safety issues..hopefully i didn't miss something and it only cycles manually and not automatically .....if it's auto with the chain at the bottom being exposed. ...with my cats I could see an unintentionally amputated tail with the way they like lying under things. With the way my cat isn't spooked by much he'd just lay there until it was too late. Or my other cat attacks anything that moves and would stick his paw in the moving chain and get a manicure the hard way....Another thing is what about when your cats are older or maybe get sickly? Climbing the tree to get to the box may become difficult or be a bad idea for older less agile cats (maybe borderline cruel) Would you tell your grandmother... "Sure, you can use the bathroom, it's on the 4th floor on the other side of the maze". I'm sure mine would punch me in the face if I said that to her . Also, for what you spent on materials and equipment to build it....you probably could have bought a litter robot or equivalent. ..maybe even 2 of them....sensors, electronics, ball screws and pillow blocks aren't cheap. I get it...it's a stick it to big corporation project or I can do it better project, but there should be a line between that and futility. Just my 2 cents. You accomplished what you set out to build....so congrats on that. Time to refine it.

Could have scooped the box 5 times by the time that does 1.

That ridiculously made. But clever.

As an architect I look at this, impressed, and then think....shoulda gone with birch plywood

That is amazing, I tip my hat to you and the love and dedication you have shown for your cats

Best DIY one I've seen yet! Would love to see an updated version that is smaller, made from stainless steel, and includes, a light and air filter. You are talented :)

Great job! Add a bathroom ventilation fan to the outside and it's complete!

Take my MONEY!!!!

Great video! Just a thought.... holding 2 weeks of litter in the room will still smell. If you could figure a way to hook the shoot so that it dumps it down a shoot to an external trashcan - that would be awesome.

I didn't know you could do that with excel! amazing design!

Well done sir. I appreciate the over-engineering of the mechanics. May I suggest adding some synthetic waterproof sheets around the inside of the business area. I see it's painted, but something as simple as sheet flooring or laminate (formica) would hold up better in the long run. Not being a software guy, I would have used a few logic gates to control the motor, but hey, if you can use a computer, why not? A big thumbs up!

You should post more videos if you have more wonderful contraptions/inventions. Love this stuff.

Dayum. What a great cat owner, very dedicated!! 👏🏽👏🏽

Ha! This is awesome! How did you come across the hardware?! Ball screws!!!! You were not messing around! Nice work, I love when people go all in and really make something right
