I did some marketing consulting for the "inventor" of citikitty (was on Shark Tank as you probably know). I just sent her the link to the article telling her she needs to invent some kind of consumable to her kit to get future residual income. I was half serious half kidding.
Interesting I don't use her product but we do have a cat.
She might like it. Although one potential issue is scaring off people by mentioning "germs". In other words putting an idea that didn't exist in many people's heads that they never thought of. Although also possible it would result in increased business as well.
