Here's why:
* Different Species: Rabbits belong to the family *Leporidae*, while other animals, like cats, dogs, or humans, belong to different families altogether.
* Genetic Incompatibility: The genetic makeup of different species is so different that they cannot reproduce together. Their DNA is incompatible, and offspring would not be viable.
It's important to remember that breeding between different species (also called hybridization) is rarely successful and often harmful to the animals involved.
