- Wildlife patients may hide symptoms to avoid being targeted by predators, making diagnosis challenging.
- Seals can have hidden injuries detected using a thermal camera, revealing tissue damage or infections.
- Domestic cats have slit pupils for nocturnal vision, while lions have round pupils, with theories on the difference.
- Anesthetizing big cats like tigers involves using a DOT to deliver drugs into muscles, not with a face mask.
- The placebo effect may work on animals indirectly through human perception, as seen in a study with dogs.
- Snakes' gender is determined using sexing probes inserted near their bottom, with males having a deeper gland.
- Giraffes have the same number of neck bones as humans, just elongated, with long neck bones.

Tail behavior and grooming habits of animals.
- Water trucks raise their tails when running away to follow each other, while domestic pigs have curly tails to prevent tail-biting injuries; farmers bred pigs over centuries to have curled tails to avoid infections and paralysis. Big cats like tigers and lions groom themselves like house cats, with hairballs being rare due to their large stomachs and minimal hair, usually passing through in their feces.
