try making this DIY SubQ Harness:https://www.reddit.com/r/RenalCats/s/OjTnck4pOK the ones I bought 3 weeks ago on amazon: - 2x4 strips with adhesives- 2x18 Cinch straps (12pk) it’s made the process so much better and you can even get a wall hook or just a hanger to hook the bag up-to something while you just chill with your cat or keep them from running. That would make doing it solo much better. if you do it in the bathroom you could hang it from the shower with a hanger. Goodluck!
