Rabbits are cute, fluffy and innocent

I love rabbits. They're cute, fluffy and innocent. My practical brother, however, bought me this rabbit killing kit:

To pay him back for his bloodlust and creature cruelty coercion, when he was showing me the knife and warning me about how v e r y sharp it was, he cut his finger! He he... Now, one of these items is simply a fire starter, so that is quite useful. The loopy things are snares; they strangle the rabbit, or ensnare it in some other painful way. I've seen Watership Down, more than once. I cannot imagine that I would ever be hungry enough to feel the need to use a snare to catch a rabbit. But I think they may have some other practical or decorative function. Suggestions please.

The previous owner of our property had a bank of eight rabbit hutches right next to the first cottage, a little Leporidae highrise. I don't know if he caught these, or if he bought them as a reproducing food source. I have eaten rabbit and hare, and no doubt will do again, but can I butcher one myself? If I happened to come across one without having to snare it... there are butchering instructions in my self sufficiency book:

Hmmm... we'll see. I haven't actually seen any rabbits out in the open on our land, but there is certainly evidence of rabbits. I imagine the ubiquitous giant-sized buzzards keep them in their burrows and under hedges for long spells. I am slightly worried that they'll carry off our cat. The buzzards, not the rabbits.

Did you know that rabbit urine is great for lemon trees?
