That is the most made up sounding fact I’ve heard in a long time.

Not really. People started having issues with teeth when we switched to farming and went from a diverse diet to a pretty poor one (grain, grain, grain).

Sugar, high fructose corn syrup, and acidic drinks such as coffee and cola does almost all the damage.

Correlation causation etc. I'm gonna start eating whole mice. It's a nice compromise. They're velvety.

Or even just eat Rabbits, as they're already a common recognised food animal?

You need to try chinchillas.

There's a scene in the 1983 movie "Never Cry Wolf" about that. Apparently they taste better with ketchup.

I recommend rats, we have them in surplus around here-parts.

Are you a cat?

Got a source for that? Seems like BS, tbh.
