Who is to be the judge of what the definition of 'wasted? is?
If a parent buys a cat for a child they should ensure the child is able and willing to care for it in advance, and if the child does not care for it adequately then it's the responsibility of the parent to feed the cat. There's no need to remove the cat in this situation as cats will remove themselves if food is on offer.
Perhaps you would use a pen from a desk, but if the child owner was there it would be right to ask permission first.
Respect for children includes respect for their stuff.
Just noticed this......
Haven't watched yet.
