Here are some factors that affect their food consumption:
* Size and Age: Larger, older tigers need more food than smaller, younger tigers.
* Activity Level: More active tigers require more energy and will eat more.
* Availability of Prey: If prey is scarce, a tiger may have to hunt for longer periods and eat more when it succeeds.
It's important to note that captive tigers may eat less than their wild counterparts, as their food is readily available and they are not expending as much energy.
