My Sisters Labrador called Sasha has been getting fat eating the cats food and the poor cats are losing weight :(

Since Sasha is the leading lady in some of my productions I thought I should find a way to help her with her dieting by developing a Dog-Proof Cat Feeder!

I've added a short video showing it in use here:-

The early prototype started well but Sasha worked out how to get the loose cap off the top so I then added a secure screw on lid.

The way it works is that dogs (apart from the tiny varieties) have almost double the paw width that cats have and the slots to the cat food are too narrow for a dogs paw but more than enough for a full size tabby. The cats paw out their meal and then more cat food comes down the hopper. Most cats won't overeat so it's generally safe to trust them with there own food.

The hopper can take approximately 8 standard cat meals so if you go away the cats can feed themselves!

The three cats all quickly worked out how to use it and now Sasha can get slim for Summer :D

Now if you want to get real tricky with this print you can print it in a semi-transparent filament so you can see how much cat food is left :)

You can check out my other designs here:-

Printer Brand:










I printed this in a tough PLA with 3 perimeters and 4 top and bottom layers. Supports are needed for FDM prints but are minimal. Now if you want to get real tricky with this print you can print it in a semi-transparent filament so you can see how much cat food is left :)

What shoud the dimensions be? Its showing almost 200mm wide for me, sounds off going by the video

that's around the diameter of the base

Seemed smaller in the video, gonna have to scale it back a bit to fit on my printer, thanks for the reply.

Australian domestic cats are 30% bigger ;-)

it is good for slow feeding too

Actually cats shouldn't eat the hard food anyways. Check out catinfo.org. Best site ever for cat lovers. We had a fat and happy male cat 4 years ago but had to be put on insulin shots. I switched him and his sister over to soft food and the insulin shots went away and he lost 4 pounds and sometimes runs around like a kitten.

Yes, I think you're generally right there though I think this particular dry food is semi-soft and a bit more balanced than most. I'll pass on your recommendation to my Sister though. They adore their animal family so I'm sure they only want the best for them :)

I neither have cats nor dogs due to an allergy but this is definitely a very neat and cute idea.

Thanks Drato, when I get a chance tonight I'll put together a youtube video I took so you can see the feeder at work without the allergy risk :)

I've just added a short video showing the feeder in use :)
