Video from Cornell on how to trim a cat’s nails. It really is a small thing once you get your cat used to it. I timed doing three cats at home once, I had all three of them done in less than four minutes.
I also agree with the sentiment above that if you can’t trim the nails, you probably can’t place the Soft Paws well, either. I’ve never seen them stay on very long - it’s normal for cat’s nails to shed. The entire outer sheath can come off all at once, leaving what looks like a hollow nail behind. When that happens, the nail cover comes with it. This is why, if you read the instructions on the nail covers, they instruct to trim the nails first anyway. This is because, if you’ve seen enough nail trims, if you trim a nail when the sheath is close to detaching, the trim will make it detach. So trimming first will help remove any sheath that may make the nail cover fall off in the following few days. If you don’t, you may have to keep doing single nails every few days, and who wants to do that much cat wrangling?
