Although it is forbidden to touch chametz on Pesach, for fear that the
person will come to eat it (see Orach Chaim 446:3, and Magen Avraham
5; Mishnah Berurah 10), this applies to circumstances where there is a
concern for eating the chametz. Under ...
From the Wikipedia article on Chametz (leaven):
The Torah has several commandments governing chametz during Passover:
The positive commandment to remove all chametz from one's home (Exodus 12:15).
Not to possess chametz in one's domain. (Exodus 12:19, Deuteronomy 16:4).
Not to eat chametz, or mixtures containing chametz (Exodus 13:3, Exodus 12:...
Hacham Ovadia Yosef discusses this issue in Yabia Omer Helek 7 Siman 44 in terms of the kinneret, which supplies water for most of israel. Kibbutzim along the coast are KNOWN for dumping hametz into the water. He answers that hametz dumped before pesach is nullified in 60. During pesach, he applies the concept of "tzonen bitzonen". Since the hametz and water ...
There is no special Talmudic dispensation regarding oats.
The Mishna lists a grain called שבולת שועל as able to become Chametz. Most Rishonim don't identify that grain with what we call oats. Some Rishonim do identify that grain with what we call oats.
Your point is one very strong proof for the former position, according to which indeed oats can't become ...
There are really two parts to your question. One is: do the rules of Chametz apply regardless how it is ingested?
On Pesach, one may not consume, own or derive benefit from items that
contain derivatives of the chameishes minei dagan - wheat, barley,
spelt, oats, and rye.
The second part of ...
This list from the Star-K has many items that you can feed your cat on Pesach.

foods for Passover, because while Ashkenazim do not customarily eat
kitniyot, they are permitted to own and benefit from them.
R' Cohen in Dose of Halacha quotes R' Ben-zion Abba Saul who does allow you to use flakes, though writes that others advise you to buy worms, etc. or something that is chametz free.
Rambam (Chametz Umatza 4:8) and the Shulchan Aruch (OC 442:4) write that one does not need to dispose of a mixture containing chametz that is totally inedible (by humans). ...
The Radvaz (Teshuvos, chelek aleph: 135) and the Chayey Adam (119:6) explain that the reason we clean cracks and crevices from chametz is because maybe we may come to eat it on Pesach (because it might get into food).
Otherwise, the Gemara Pesachim on 6b says that crumbs are not important at all. The Magen Avraham (S.A. 434) even says that crumbs are "batel"...
Based on 45+ years of marriage, I can assure you that whatever you say to your wife (other than the two most important words in a marriage) would probably not help. Rabbi Moshe Heinemann in his pre-pesach shiurim will emphasize that you do not have to go overboard (and the women do not accept that). Rabbi Avigdor Miller in his tapes on the subject tries to ...
I do not understand why it would be a problem a coupon is a document which entitles one to a discount,but in no way does it give ownership of that item to the holder of the coupon. The item becomes theirs when purchased which is after peasach.
But rabbis in even some of the most Orthodox associations say chometz
does not refer to all leavening.
"There is nothing wrong about a raised product at Passover per se,"
said Rabbi Moshe Elefant, executive rabbinic coordinator and chief
operating officer of the Orthodox Union'...
Per the Yalkut Yosef 448:5:
It is permitted to eat Chometz on a Shabbos which is immediately after Sheviyi Shel Pesach - there is no Muktza involved, and if it was sold to the non Jew according to Halacha you may eat it on the day of Shabbos immediately after Sheviyi Shel Pesach. However you have to be extra careful not to take the chometz on Sheviyi Shel ...
The Shulchan Aruch (OC 555:3) rules that if one kneaded his dough with hot water it is forbidden, the assumption being that heat makes something become chametz quicker. This is also seen in the rule (559:1) not to knead the dough in the sun or in a room with a hot oven. Moreover one can leave dough in cold water indefinitely to prevent its becoming chametz (...
The easiest thing to do would be to contact a kashrut supervising agency and they would be able to answer, item by item. They may, though, not want to give rulings on individual products if the overall storefront is not kosher for passover or using their general supervision services. Some groups, like the OU had a hotline available in the days before ...
Aruch Hashulchan 496:5 says that it is forbidden for a Ben Eretz Yisrael to eat Chometz in Chutz L'Aretz on Acharon Shel Pesach.
ויש מי שאומר דבן ארץ ישראל הבא לחוץ לארץ – אסור לו לאכול חמץ באחרון של פסח בכל עניין, אפילו דעתו לחזור. ונכון הוא, דזה גריע ממלאכה.
Star-K says it is forbidden.
Q. During a Pesach visit to the zoo, may one purchase the feed for the
animals? A. No. This feed is often chometz and should not be
purchased or fed to the animals during Pesach

To summarize the comments (as well as my personal experience):
It is required to burn (or otherwise destroy) a small amount of Chametz (see here for some technical stuff). Chametz that is typically burned is a small, token amount of opened food. For many (if not most) people that I see, it is ten small croûtons or bread pieces that are customarily ...

THE LAWS OF PESACH by Rav David Brofsky Shiur #2: The Laws of Pesach Defining Chametz (1)
R. Yosef Karo (Shulchan Arukh 462:1-4) rules in accordance with the view of Rabbeinu Tam and the Rambam, who permit matzot made with fruit juice. The Rema, however, concludes that Ashkenazim should refrain from eating matza ...
Shulchan Aruch O.C. 448:5 rules that chometz which is found in your home after Pesach, even if you nullified it, is forbidden. The Tur there (cited by Magen Avraham and Taz) explains that we are worried that a person will say he nullified it even if he didn't. This isn't a problem for those crumbs that you don't want anyways. But for that box of cheerios ...
In the fall of 1911 (early 5572), Rabbi Shalom DovBer of Lubavitch sent Rabbi Shlomo Zalman Havlin along with seven students to establish the "Torat Emet" yeshiva in Hebron, Israel.

The Chayei Adam says that ...
The OU has a long article explaining the possible issues with aluminum foil and aluminum pans. Due to the concerns raised in the article there are those who manufacture aluminum in a way to avoid a possible issue.
My understanding is that on Pesach when people are more careful than usual, even those who rely on the leniencies during the year may be extra ...

Kefula means "doubled over." We have the same root word used in the morning bracha "zokef kefufim" (He straightens those who are bent over), or in upcoming Daf Yomi, "tenai kaful" (a legal stipulation where both possibilities are spelled out, if x then y, but if not x then z).
Then there's nefucha (swelled matzah), typically a bubble, similar in appearance ...
