Talking Talmud

What are kosher animals? What are non-kosher animals? That is, from the signs listed in the Torah for domesticated and non-domesticated animals -- such as split cloven hooves and chewing its cud (for the former category). Ditto re birds -- excluding predator birds, where the forbidden ones are listed explicitly (or perhaps for the sake of deriving a general rule). Likewise for the few kosher creepy-crawlies. And fish (fins and scales). Plus, what if there is no tradition with regard to a certain animal (eg: duck; turkey). Also, the signs of the undomesticated - which might seem superfluous, but they permit the special fat, which might appear to be incorrect, so it's explicit. Plus, a unicorn. With caveats on the horns making various goats and their cousins

What is the status of a treyfa animal after it has been declared a treyfa? For example if a hen is deemed a treyfa, what is the story with her eggs, for example? It will depend on whether the "father" of the eggs was also a treyfa, if the eggs were unfertilized, and the timing of when the eggs began growing (before or after the treyfa status). Also, worms in a melon when it grows from the ground or in dates that are stored in a jar -- when is that a problem of kashrut or not? Based on the presumption that invertebrates don't survive 12 months. Plus, mosquitos who officially lasted 7 years, but, apparently, that's not a real issue for the count.

If a bird has a dislocated femur, the bird is nonetheless kosher. But it seems that the same sage said that it was not kosher - in Pompedita, leading to an observation that different stringencies applied in different communities. One element of the decision being where the break occurs in the bird's leg. [Who's Who: Rabbi Shimon bar Halafta] Also, efforts to demonstrate that an animal that had been dubbed a treyfa is really not a treyfa - experiments by R. Shimon bar Halafta to disprove Rabbi Yehudah, including the shenanigans at an ant hill that apparently has no king.

2 mishanyot! 1 - A list of injuries or damage that render birds to be treyfot -- including a weasel that hits the bird on its head. With an apparent 24-hour testing ground to see if the animal will recover, at which point, it will be considered kosher. Also, how much of the bird would turn green in the internal organs if it were scorched for it to be a treyfa? Plus, the story of Rabbi Yehoshua ben Levi's bird that was scorched in a fire, and a color change from red to green (or green to red) being a problem.

What happens when there are injuries or defects in the lung can be benign when it's in the kidney. But when it's fine in the lung, does that mean it's automatically find in the kidney? But really, each kind of ailment or injury is specific to that same organ, because there's no guarantee that it won't be a problem in a different one. Also, the case of a "shriveled lung" - at the hands of heaven, and not as a result of an animal's attack, per se. Maybe it shrunk in fear... Well, in that case, the animal would either be kosher or a treyfa, depending on how the text is to be read. Plus, a method of figuring out whether the lung can be expanded, which tells you that the animal would have recovered from the shriveled lung(s). And if they don't, then the indication is that the animal was treyfa.

Investigating (final?) details about what makes an animal a treyfa - in terms of injuries. Is there a rule of thumb, or is the list of what makes an animal a treyfa complete, in terms of listing all the possibilities? But then the Gemara walks back the question... Also, a new mishnah! On how much damage can be done to the trachea (and other body parts), and the animal remains kosher. Plus, a comparison between two mishnayot that seem to contradict each other in methodology. Also, more on the perforation of a trachea -- and how the measure that keeps the animal kosher is less than an Italian issar - but that wasn't helpful in Babylonia, where they weren't familiar with the coin. Plus, the job of the money-changer who tried to stand up in honor of Rabbi Yochanan, who declined the honor because of the job at hand. Plus, the time the tradesmen stood up to honor those bringing their first fruits (bikkurim) to Jerusalem.

When a kosher animal is clawed by a non-kosher animal - when do we take it as a given that it will be considered a treyfa -- or really to the contrary? What if the animal is a cat? Or a fox? Or a hawk? Why is the question what animal did the clawing, as compared to asking what damage has been caused? Plus, determining what happened to the clawed animal, when nothing was really seen. Where the clawing animal's claws poisonous? If so, doesn't that harm lead to the animal becoming a treyfa? The sages are establishing rules of thumb so that they can make assumptions about the clawed animal, rather then investigating every case.

A majority of broken ribs -- seems to be a treyfa. But what is the way in which they were broken? Does having been attached to the vertabrae make the process that much more challenging? If the ribs are dislocated and the spine is not damaged. Also, an animal that is clawed by a wolf (or a predator of that size or larger) will render the victim animal a treyfa (and predator birds from a "netz." But what about a small animal, like a cat?

If/when an animal falls from a roof -- if it breaks its limbs, the question shifts to focus on whether the injury is common (like rheumatism) or unusual, like a broken spine. And the concern here is only for the common case. Also, a bird that fundamentally crashes on water is considered fine if it can swim the length of its body -- upstream. Plus, what if a bird falls into all kinds of other substances?

Perforated intestines are likely to be sealed by internal mucous, which would leave the animal kosher. The Gemara then traces Rabbi Shimon ben Gamliel's statement on this point - namely, that it would be kosher. And Rabbi Shimon's view on mourning -- that a mourner who first hears about the death late will join the count with the family that is sitting shiva if he is close enough to join them (and then continue his own count afterwards). Until the end of the discussion, when Rabbi Shimon ben Gamliel's approach is rejected, and Rabbi Shimon's is upheld. Also, the inner and outer paunch - with a lot of detail regarding what needs to be intact to be able to call the animal kosher. But the sages themselves have a lot of questions here.
