That reminds me I 'experimented' early on eating dry cat food, which is not one of my happy food memories, it actually wasn't that bad though--pretty much tasted how it smelled.
There was actually a kid on a anti-seizure diet (high fat, high protein, almost zero carbs) that would only eat cat kibble.
Dr. said it was fine if the kid wanted to eat it....
Blech...
On a similar topic, my dad always liked trying things that were different. A lot of people thought the sugar on tomatoes was odd. He also liked limburger cheese and herring on New Year's. One favorite story was about the time he was at a dinner where possum was served. The host was greatly complimented until the other guests found out what they had eaten.
