Generally, mortality in red pandas is similar to that of other mammals, but is higher in males.

The mortality schedule in red pandas is similar to that of other mammals, being highest in the youngest, (0-1 year,) and oldest, (7-12 years,) age classes with a decline during middle age (1-7 years.)

In captivity, red panda litter size ranges from one to four with a mode of two. Litters of two and three young have the lowest juvenile mortality. Survivorship of the young is independent of maternal age and experience. Generally, mortality in red pandas is higher in males and increases significantly with higher inbreeding coefficients. The sex ratio in a sample of 100 infants born in 78 litters was 48 males to 52 females.
