👉 Underbreeding is a practice where animals are kept in captivity with their parents, rather than being born into a litter. This can be done to increase the number of offspring that can be produced, as it increases competition among siblings for resources like food and space. In some cases, underbreeders might choose to keep multiple litters of identical offspring, which is known as "cross-breeding." However, this practice is not recommended because it can lead to genetic disorders in the resulting offspring.
