Predatory big cats, such as lions and tigers, have round pupils instead of slit-shaped pupils like domestic cats. This is because their round pupils allow for a greater range of vision and depth perception, which is important for hunting and stalking prey in various lighting conditions. Additionally, round pupils also allow for better low-light vision, which is essential for hunting at dawn and dusk. Overall, the round pupils of big cats are better suited for their predatory lifestyle compared to slit-shaped pupils. **

A feeding grid can be useful for controlling the amount of feed each animal receives and reducing competition during feeding. Ultimately, the best option will depend on factors such as the type of animals, feeding behavior, and management practices. **
