Of course that's not the point of the ad and I don't blame them for not making it a philosophical discussion, but it's the same approach that Madagascar uses (spoiler for a 20yo movie) to resolve their main conflict and both feel like cheating - if the penguins can think, I always thought, then so should the fishes.
I think the argument is “meat is murder because you can survive without it”. Maybe that doesn’t work for the wolf, but I mean, it’s literally a story being made up for a child, and animals in those are allegories for humans.
I can choose to not eat meat and live healthily, but I’m not going to feed only vegetables to a pet cat, who needs something different. To each what they need, as ethically as possible. When you can minimise harm, do.
