Dogs are highly social carnivores with acute senses of smell and hearing. Their anatomy reflects tens of thousands of years of co-evolution with humans, resulting in enormous breed variation but a shared underlying body plan.

Cats are obligate carnivores with a flexible spine, retractable claws and exceptional low-light vision. Their metabolism is adapted to a high-protein diet and they require specific nutrients such as taurine.

Rabbits are strict herbivores with continuously growing teeth and a large cecum where fibre is fermented. Their gastrointestinal tract must keep moving at all times โ stasis is a true emergency.

Parrots are highly intelligent birds with a hooked beak, zygodactyl feet (two toes forward, two back), and complex social needs. Their respiratory system uses air sacs and is exceptionally efficient โ and sensitive.
