What is the smallest animal that eat rabbits?

There isn't a single "smallest" animal that eats rabbits. It depends on what you define as "smallest" - by weight, by size, or by age?

Here are some contenders:

By weight:

* Weasels (especially long-tailed weasels) are quite small and can kill rabbits, especially young ones.

* Stoats are slightly larger than weasels but still relatively small and capable of killing rabbits.

* Ferrets are domesticated weasels and can also be quite small.

By size:

* Snakes like garter snakes and rat snakes can swallow rabbits, especially young ones.

* Birds of prey like hawks and owls can hunt and kill rabbits, but some species are smaller than others.

By age:

* Young foxes are smaller than adult foxes and can hunt young rabbits.

It's also important to remember that size doesn't always determine prey. A smaller animal might be able to take down a larger rabbit if it's more agile, faster, or has a better hunting strategy.

Ultimately, the answer to your question depends on how you define "smallest" and which criteria you prioritize.
