Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments Letters of credit – The Company had $1.3 million of outstanding letters of credit related to normal business transactions at September 30, 2023. These agreements require the Company to maintain specified amounts of cash as collateral in segregated accounts to support the letters of credit issued thereunder, which will affect the amount of cash the Company has available for other uses. The amount of cash collateral in these segregated accounts was $14.1 million and $14.7 million as of September 30, 2023 and September 24, 2022, respectively, and is reflected in “Restricted cash” on the Company's consolidated balance sheets. Purchase commitments – Production and purchase agreements (primarily for grass seed and grains) entered into in the ordinary course of business may obligate the Company to make future purchases based on estimated yields. The terms of these contracts vary; some have fixed prices or quantities while others have variable pricing and quantities. For certain agreements, management estimates are used to develop the quantities and pricing for anticipated purchases, and future purchases could vary significantly from such estimates. Contingencies The Company may from time to time become involved in legal proceedings in the ordinary course of business. Currently, the Company is not a party to any legal proceedings the resolution of which management believes could have a material effect on the Company’s financial position or results of operations with the exception of the proceeding below. In 2012, Nite Glow Industries, Inc and its owner, Marni Markell, (“Nite Glow”) filed suit in the U.S. District Court for New Jersey against the Company alleging that the applicator developed and used by the Company for certain of its branded topical flea and tick products infringes a patent held by Nite Glow and asserted related claims for breach of contract and misappropriation of confidential information based on the terms of a Non-Disclosure Agreement. On June 27, 2018, a jury returned a verdict in favor of Nite Glow on each of the three claims and awarded damages of approximately $12.6 million. The court ruled on post-trial motions in early June 2020, reducing the judgment amount to $12.4 million and denying the plaintiff's request for attorneys' fees. The Company filed its notice of appeal and the plaintiffs cross-appealed. On July 14, 2021, the Federal Circuit Court of Appeals issued its decision on the appeal. The Federal Circuit concluded that the Company did not infringe plaintiff's patent and determined that the breach of contract claim raised no non-duplicative damages and should be dismissed. The court affirmed the jury's liability verdict on the misappropriation of confidential information claim but ordered a new trial on damages on that single claim limited to the "head start" benefit, if any, generated by the confidential information. The Company intends to vigorously pursue its defenses in the future proceedings and believes that it will prevail on the merits as to the head start damages issue. While the Company believes that the ultimate resolution of this matter will not have a material impact on the Company's consolidated financial statements, the outcome of litigation is inherently uncertain and the final resolution of this matter may result in expense to the Company in excess of management's expectations. The Company has experienced, and may in the future experience, issues with products that may lead to product liability, recalls, withdrawals, replacements of products, or regulatory actions by governmental authorities. The Company has not experienced recent issues with products, the resolution of which management believes would have a material effect on the Company’s financial position or results of operations.
