Is this the biggest Siberian tiger in the world? He/she is captive and tame at least with this man. I don’t know who he is. Possibly one of the private zoo owners of America. The Siberian tiger is the world’s biggest cat anyway but of course they vary in size and weight. The maximum seems to be either 716 or 790 pounds depending on your source but I am sure people will claim that this cat can be heavier. Siberian tigers are difficult to weigh 😉 . Especially when they are wild!
The world’s largest cat is the Hercules a liger (lion/tiger hybrid) but this Siberian appears to be a similar size but a bit smaller. I think Hercules weighs about 1000 pounds.
