it's very merciful. She's still able to eat, she has a shelter, and she's still able to have kids. Of course, mister will do something about all her desires I'm sure...
Pets have their mating privileges revoked, so "munch munch happiness" becomes at least half their life. To be supplied with an abundance of very tasty sweet sweets while unable to enjoy them is a deliciously tasty punishment.
This is pretty much an example of how to give yukkuris a fate worse than death.
Yeah she still can eats, but can savour anything, so no "happiness", no happiness = no take it easy.
But she still can breed some would say, little ones bring easiness:
But as kodokueajy said, owners have the absolute say about having kids or not, and i doubt mister would ever let her have them, unless they are meant to be used to maker her suffering worse, and shelter alone means nothing, a cardbox is shelter for them, but without tasty munch munch and other easy stuff it lacks any source of easiness, same for caves and other "shelters".
In the end, the most delicious aspect of the punishment is that the mister shove it in the face, and not just an average passing it over her face, but a blatlant and violent shove, pushing her, stomping her with the shove, making sure she feels with with all her being.
This may look merciful, but no man, this isn't merciful, she wished she died, humans can relate to that, people think that as long as we can sleep, eat and have cover over our heads we are fine, but if we are forced into a monotonous life, a tasteless life, without any form of extra excitement and such, we wouldn't be able to feel humans, but maybe we would feel like zombies or robots, still moving around, without any enjoyment or any feeling of fulfillment, only, flavourless routine.
