If a cow or goat finds your item are they gonna return it to you?
I learned the ethics of lost and found items in a Hillel Academy where they brainwashed me into believing that judaism considers ethical behavior so important that the learned rabbis argued for days about the possible moral obligation a jew has if they find a pile of coins by the side of the road, depending on whether it's arranged in a certain way that could be identified by its owner as opposed to being strewn randomly, etc. But they left out the most important part in my schooling there up to 6th grade, which is that a jew has no moral obligations to goyim.
You could spend many months reading and studying the 419 pages of this PDF and only maybe at the very end, maybe maybe, you'll find what they didn't teach me in 6th grade, but the most crucial fact will elude most readers.
pages 88-89:
Come and hear: If one finds therein19 a lost object, then if the majority are Israelites it has to be announced, but if the majority are heathens it has not to be announced.20 Now who is the authority that lays it down that we go according to the majority if not R. Simeon b. Eleazar? You must therefore conclude that R. Simeon b. Eleazar says this only where the majority are heathens, but not where the majority are Israelites! — [No.] This is the view of the Rabbis. But then you could conclude therefrom that the Rabbis accept R. Simeon b. Eleazar's view in the case where the majority are heathens! — Admittedly, therefore, this21 represents the view of R. Simeon b. Eleazar, and his ruling applies also to a case where the majority are Israelites, but here21 we deal [with a case where the money was] concealed.22 But if it was concealed, what has [the finder] to do with it? Have we not learnt: ‘if one finds a vessel in a dungheap, if covered up he may not touch it; but if uncovered he must take it and announce it’?23 — As R. papa explained:24 [The reference is] to a dungheap which is not regularly cleared away, and which [the owner] unexpectedly decided to clear away — so here also [the reference is] to a dungheap which is not regularly cleared away, and which [the owner] unexpectedly decided to clear away.25
