What is Reddit's opinion of Ultra-Bitter Training Aid Spray – Chewing, Biting, Licking Deterrent for Dogs, Cats, Horses, Rabbits, Ferrets, Birds - Safe for Pet’s Skin – Can Also Protect Garden from Deer and Pests (4 fl oz.)?

From 3.5 billion Reddit comments

Not tried it myself, but maybe something like this?

Or possibly the stuff that humans use to make their nails taste bitter so they don't bite them? Definitely check it is non-toxic to cats first though - I imagine it probably would be, seeing as it's designed for people to sometimes get in their mouth, but it's never wise to assume these things.

Good luck!

So I'm fortunate enough to have a bun that a) doesn't have an issue with slippery/hardwood floors and b) doesn't chew baseboards. I still have quite a few blankets and carpets all around the apartment so he's able to run around and binky without slipping.

BUT in the past I've had issues with him and my other rabbit chewing on baseboards and I've opted for all-natural bitter sprays. They're completely safe and they just make baseboards or any wooden elements of your home taste nasty so rabbits won't want to chew them. I used this: https://www.amazon.ca/Fooey-Ultra-Bitter-Spray-4-Fluid/dp/B000FOYMFU

No but I've tried Fooey bitter spray and it didn't work. Maybe I'll try that tho. Thanks!

You could buy some bitter spray that is normally used to deter cats.
