Ok, most of these seem pretty cruel and inhumane, but what's wrong with the pet fountain? Most cats are much more likely to drink from one of those than from a bowl, which is really a health issue and not ridiculous at all.

Some of these are really not that unusual (at least not worthy of an “Eww that's so weird” reaction). Something tells me the poster is one of those people who only eats chicken sandwiches or something, day in and day out.
