How can I remove the bottom of a rounded edge can?
All the can openers I've looked at grip the lip of the can. Is there a special can opener made for this?

1. Dremel and Nail. Dremel alone can be too long and not give clean cut because the Dremel don't have guidance when cutting. I would first use a small nail and hammer to make a dotted holes along the perimeter of the can (it is safer than using knife because the nail grip to the can surface right after it starts dented) like around 1/8" apart or smaller as much as you can. That way the area than needs to be cut by dremel will be smaller.
2. Instead of dremel, you can make firs make a pilot hole with a metal puncher (like https://ae01.alicdn.com/kf/HTB1BIncNXXXXXbGaXXXq6xXFXXXh/RC-Hobby-model-Metal-Hole-puncher-HSP-1-10-Scale-Racing-RC-Car-Shell-Reamer-Drills.jpg) or (several time) with bigger nail. Afterwards you can use small tin snips to cut the rest of the lid. Tin snips can be bought at Lowes/Home Depot/home improvement stores. Adding the dotted holes liek in #1 also helps too
I'm not sure how to reply to your post -- it doesn't give me the option to reply under it. I looked up the Kuhn Rikon you suggested and I'm unclear on how it attached to the can. The one YouTube video I watched seemed to show it somehow attaching to the lip? Do you have this can opener? Do you know whether it would work on a can without a lip to attach to?
Thanks!

What I love about Dremels are the many many attachments that you can buy, including cutting wheels and mini saws. Like this one, http://www.ebay.com/itm/like/401225359745?chn=ps&dispItem=1
I'm not even a Grease Monkey, but I love this tool and it's versatility.
The ice pick suggestion is a good one but my boss is hoping for something that eliminates the risk factor altogether (we had talked about using a screw driver with a hammer to create vent holes).
Not much of a refinement but better than the knife technique-- use an icepick to pierce the bottom and release the pressure from the bottom of the can. The ice pick pierces the can much easier and you are not likely to get the ricocheted effect that you can with a knife.
I could try contacting Zupreem but I'm not sure my question is one that they'd get regularly. We are using their diet unconventionally, for an animal that isn't a primate. Keepers who feed it to primates may not need the food to come out whole.
Thanks!
Yes, contact Zupreem.
All they can do is raise their eyebrows.
But/and many manufacturers discover new or variant uses of their products from customer feedback.
Give it a shot!
Thanks!
