This is so sad, people expect animals to live in totally artificial environments, (locked in a house all day), feed them food that is loaded with chemicals, treat pets like accessories instead of living beings, and then when the animals have behavioural problems, which are caused by humans, then people want to dose them up on drugs. Of course big pharma will oblige by supplying these drugs, (at a price), they will be happy to feed peoples laziness and desire for a quick fix to the problems that people have created.
The worst thing, is that like children, pets don't get a choice.
