Actually making cats employ more hand/eye coordination to get their food is considered a healthier alternative to just laying it in a bowl. For example: https://www.google.com/search?q=cat+challenge+bowl&ie=utf-8&...
I was more focused on the "foraging" concept with regard to cats. I don't think cats forage.
Years ago we rescued a barn cat, she would wonder all over the area to find food (few mi radius): birds, mice, etc.
Barn cats are so cool! Little murderfloofs with their instincts well intact.
