The future is probably more of the same. In reply to the reader who wondered the other day if ligers (lion plus tiger) can breed and produce offspring, the answer is yes. The results give rise to big kitties with a horde of odd names to describe the crosses: ti-tigon, ti-liger (tig-liger), li-tigon, li-liger
From Messy Beast:
Female tigons and ligers are often fertile and can mate with a lion, tiger or in theory with another species such as leopard or jaguar. Tigers and ligers have been mated together to produce ti-ligers (tig-ligers). Tigers and tigons have been mated to produce ti-tigons (below). Ti-ligers and ti-tigons are more tigerlike (75% tiger). Ti-tigons resemble golden tigers but with less contrast in their markings. Lions and ligers have been mated together to produce li-ligers. Lions and tigons have been mated to produce li-tigons. These hybrids are more lion-like (75% lion). (See also Backcrossing for information.)
Male hybrids are rarely, if ever, fertile even if they do display sexual behaviour. To date, all male ligers, tigons, ti-tigons and li-tigons investigated have apparently proven sterile. There are no authenticated liger x tigon, liger x liger or tigon x tigon hybrids. Theoretical offspring could be lion-like, tiger-like, liger-like or tigon-like, depending on what combination of genes they inherited. It is more likely that anecdotally reported offspring from supposed hybrid-to-hybrid matings actually resulted from unobserved additional matings of a hybrid female with a pure-bred lion or tiger.”
So it’s the girls keeping the thing going.
