Eurasian Lynx vs Perentie

I was thinking the tail would be more of an issue than the bite. A cat will be focusing on the head/neck, so it will be hard for the lizard to land a bite.

Eurasian lynxes regularly prey on piglets, and only tom lyxes occasionally prey on adults (two cases reported in a 10 year study in the Bialowieza forest). There is no direct information on the age/size or state of these pigs, though an adult boar in the Bialowieza forest should weigh at least (in extreme) 40 kg and about 60 kg on average, which is about 2-3 times the weight of the cat. Even if it is almost certain that these cases involved ambushes, I still regard it as an impressive predation and as proof that an Eurasian lynx has the capacity to kill a same weight competitor like a wolverine or a stray dog.

Obviously a healthy adult boar is too much for a lynx in a fact to face match, and more so because these pigs forage in groups and the lynx is a solitary hunter. Thus lynxes give them a wide berth. The articles on lynx predation in Bialowieza mention that adult boars usurp lynx kills even when the cat is present. But an adult boar is already a dangerous and hard prey for wolves and leopards, so we shouldn't expect a smaller lynx (20-25 kg) doing better.

I have an article on the effect of snow and climatic factors on the predation of wolves and lynxes in the Bialowieza forest. At least one of the two adult boars taken by a lynx male was killed in a very mild winter with very little snow, therefore, there is a good likelihood that it was not a staved ultra weak pig.
