We've taken the worst quality,
least safe feeding system in America, one that is potentially hazardous and potentially toxic, and taken it to a level where it's U.S. food grade and certified for human use.
We do need to take every possible precaution to keep ALL cats and kittens
safe, which is a valid argument used by many «experts» for charging a substantial adoption fee; also, to offset a portion, at
least, of the cost of sheltering (
feeding, innoculations, exams, etc.) until adoption, many shelters have that policy.
