Diamond Naturals Indoor Cat Hairball Control Dinner for Adult Cats

6 ingredients in this list are ones we hold sourced evidence on , and 1 of them is genuinely contested rather than merely unpopular online.

• Carrageenan · ingredient 15Worth knowingA seaweed-derived (Chondrus crispus) thickener and gelling agent used mainly in some wet and canned dog foods. Low-molecular-weight 'degraded' carrageenan (poligeenan) is inflammatory in lab-animal studies and is not permitted as a food additive, but food-grade undegraded carrageenan (E 407) is authorized by regulators; EFSA's 2018 re-evaluation kept only a temporary group ADI of 75 mg/kg body weight per day pending better data, and its specific effect in dogs is unresolved.
• Beet Pulp · ingredient 8Well supportedThe fibrous material left after sugar is extracted from sugar beets, included as a moderately fermentable fiber source (commonly around 5 to 7.5% of the diet). Controlled feeding studies show it supports firm, good-quality stools and short-chain fatty acid production without impairing overall nutrient digestibility, so the 'cheap filler' characterization is not supported by the evidence.
• Brewers Rice · ingredient 5NeutralAn AAFCO-defined ingredient consisting of the small, broken fragments of rice kernels separated during milling. It is a digestible carbohydrate and energy source nutritionally similar to other rice; the 'brewers' name reflects how the fragments are sourced, not lower nutritional quality.
• Powdered Cellulose · ingredient 6NeutralPurified plant cell-wall fiber (typically from wood pulp) used as an insoluble-fiber source, bulking agent, and anti-caking aid, often in weight-management diets. It is not absorbed and is poorly fermentable, so it firms stool and dilutes calories but yields little of the short-chain fatty acids that more fermentable fibers produce; EFSA's 2018 re-evaluation found no safety concern and no need for a numerical ADI.
• Guar Gum · ingredient 9NeutralA soluble, viscous fiber from the guar bean used in small amounts to thicken and stabilize foods, mostly wet formulas. At higher dietary inclusion it can lower the digestibility of dry matter and protein in dogs, but it also produces metabolic effects such as reduced post-meal insulin and cholesterol; at the low levels used as a thickener these effects are minor.
• Taurine (supplemental) · ingredient 14NeutralA sulfur amino acid that dogs can normally synthesize from methionine and cysteine, so it is not classically essential for them. However, some breeds (e.g., golden retrievers) and some diets are linked to low taurine status and dilated cardiomyopathy: an observational study (Ontiveros 2020) associated non-traditional, largely grain-free diets with taurine deficiency and DCM-consistent echocardiographic changes in golden retrievers, though causation and mechanism remain under investigation.
