Zip Ties Wire tie help with sharp ends

Hi. Building my first c and c cage. It's all done but the coroplast. I used the round connectors that came with the cubes but also decided to add wire ties for extra support. I may have got a bit carried away with them when making the folding cage top but that's another story! My question is about the wire ties though. I personally have three old scars on my left wrist from getting cut with the ends of these things about a year ago. I repaired a plastic lid from one of those drawer units and kept cutting my wrist till I realized what was happening. I don't want my toddler grandkids to get cut nor my guinea pig who is a baby. I plan to move her to the new house tonight as she is in a starter cage now. So I guess I was wondering what you all do. If you cut the ties really close they tend to open up and if you leave a fraction of an inch they can cut. I was debating about using electrical tape or even duct tape to cover each wire tie. I know most of you must think this is a bit too cautious but my scars are a reminder of how sharp these can be. Thanks
