Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of agar as a feed additive for pets and non‐food‐producing animals. Owing the lack of information, the FEEDAP Panel is not in the position to conclude on the safety of agar for pets and other non‐food‐producing animals and for the user. The FEEDAP Panel concludes that the additive is efficacious as a gelling agent, thickener and contributes to stabilise canned pet feed. No conclusion can be drawn on the efficacy of the additive as a binder.
