Alternative Diet

A red panda is kind of like a fox, and eats bamboo. If it had massive dred-tails, it could still catch bamboo. And it would probably still be cute, too.

The crab-eating fox is a canid closely related to the traditional foxes (genus Vulpes). As its name implies, it gets most of its diet from crustaceans in the wet season, and insects in the dry season, with lizards, eggs, turtles, and fruit thrown in for good measure. This kind of diet is a lot easier with a big tail than chasing rabbits would be. This diet is also pretty similar to what peacocks eat, and they manage it with their own gigantic tails.

Other options could be a badger-like diet that consists of digging things out of holes, or a strict insectivore. A diet based on plants, fruit, insects, fish, shellfish, or carrion or any combination of the above could all work.
