Cotton tails are generally tender and mild flavored regardless of age/size. Lots of ways to prepare them, and mostly good although I wouldn't want them as a steady diet.

The jackrabbits more common in my area are mostly useful as a counter for the greasy slime from the cheap meats used by some chili fanatics, and have the consistency of a handlful of chopped up rawhide boot laces - just the thing needed in some chili recipes.

Both kinds of (wild) rabbits/hares in my area (the entire US) are susceptable to infection with tularemia, and in the US some caution is recommended in handling the animals and uncooked meat. The risk of human infection isn't particularly high, but remains common enough to merit awareness if you handle wild animals or are where some tick varieties are common. Infection in a variety of animals, including cats and most rodents are known, so those with pets exposed to wildlife should be aware of the symptoms, or at least mention your animals' "hunting habits" if a mysterious illness takes them to the vet.
