A Tolerance Study of Turmeric Extract in Healthy Adult Cats.
Article in Animals : an open access journal from MDPI, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Turmeric has a long history of use as a colorant and flavoring agent. Turmeric extract (TE) is a feed additive containing at least 90% total curcuminoids, comprising mainly curcumin, desmethoxycurcumin and bisdemethoxycurcumin. The published antioxidant effects of TE in humans have sparked interest and feeding studies in companion animals. Studies describing the feeding of TE to cats are scarce and do not provide adequate toxicology data; regulatory approval is required to allow use of TE as a nutritional antioxidant in pet food. The current study describes a safety test of TE in cats. Control cats were fed a standard extruded dry diet whilst two groups of test cats were fed the same diet supplemented with two different levels of TE for four months. Physical examination, body weight, body condition score, food intake, fecal score, monitoring of adverse effects (vomiting, diarrhea, clinical signs), complete blood count, and blood biochemistry (particularly liver enzymes) were used to monitor toxicity signs. The lack of statistically significant effects of clinical or toxicological concern concludes that feeding TE to cats at a dietary level providing up to 1040 ppm total curcuminoids is safe. This allows future application of this ingredient in cat food as a nutritional antioxidant.
