You're limiting your animals.

He wasn't happy? Tough shit.

My difficulty here is distinguishing rights (or our responsibility) based upon the sentience of the animal. Baseline, I'd say we're responsible to never intentionally and needlessly cause pain (as there may be times it's unavoidable for the health and wellbeing of the animal). Killing is where I'm far more conflicted. I think it needs to always be humane. I'm vegetarian, but I've never said others need to be. I'm not vegan, and I really don't see anything wrong with housing animals for eggs and dairy and honey, again provided treatment is humane. I'm torn on leather, though, because for certain things (belts, work boots) nothing is as durable as leather, but that does require the death of animals. (I don't wear leather jackets, fur, etc., however, as there seem to be adequate alternatives to animal skin in those cases.) And for mice and rats, I'm not happy to kill them but do so because they invade the living space and carry disease — but I refuse to use sticky traps, which are torture, and I convinced my father to stop using them. I guess ultimately I think no animal should suffer needlessly, at least never by human hand (because natural predators kill their prey in horrific ways sometimes, and animals die hungry, injured, and afraid all the time in the wild). I think we should avoid killing animals if there's no purpose (e.g., hunting for sport). If we kill for food, clothing, etc., I think the death (and life, inasmuch as we're involved) must be humane and painless. There are, of course, altruistic reasons to kill, euthanizing an animal that's in great pain. I do think the more intelligent an animal is the more careful we need to be about its rights, and I'd say there's a greater obligation to a horse, a dog, or an ape, than to a mouse or a rat or a pigeon.
