Animal Gestation Calculator

Tiger Gestation Calculator

A tiger's gestation period is about 105 days, or roughly 3 months and 2 weeks, though it ranges from 93 to 112 days depending on breed and individual animal.

How to use the tiger gestation calculator

  1. 1. Choose what you know. Enter the breeding date to get a due date, or switch to the target due date mode to work backwards to the breeding date you need.
  2. 2. Refine the inputs. The calculator uses the 105-day average for this species.
  3. 3. Plan around the range. Use the earliest and latest dates and the milestone timeline to schedule checks, feed changes and preparation of the birthing area.

What to do next

How long is a tiger's gestation period?

The average is 105 days from breeding to birthing, about 3 months and 2 weeks. Anything between 93 and 112 days is normal, and a typical litter is 2-4 cubs. Treat the calculated date as the middle of that window rather than a fixed appointment.

Working backwards from a target birthing date

If you want cubs on the ground in a particular week, switch the calculator to target date mode and enter the date you are aiming for. It subtracts 105 days to give the breeding date to book, plus the earliest and latest service dates that still land inside your window.

Tiger gestation calculator FAQs

How long is a tiger pregnant?

About 105 days, a little over three months, with a normal range of roughly 93 to 112 days. Cubs are born blind and helpless at around 1 to 1.5 kg.

How many cubs does a tigress have?

Usually two to four, occasionally up to six. First litters tend to be smaller, and in the wild cub mortality is high in the first year through starvation, predation and territorial males.

Does the male tiger help raise the cubs?

No. Tigers are solitary and the tigress raises the litter entirely alone, hunting for herself and later teaching the cubs to hunt. Males can be a direct threat to cubs that are not their own.

Why must a tigress be left alone after giving birth?

Disturbance in the first two weeks is the leading cause of litter abandonment and cub deaths in managed care. Births are watched on remote cameras, food and water are left where she can reach them, and physical checks wait until she is settled.

How long do tiger cubs stay with their mother?

Eighteen months to two years. They open their eyes at one to two weeks, start following her at about eight weeks, eat meat from around two months, and need most of the next two years to learn to hunt before establishing their own territory.
