Mike VII, the tiger formerly known as Harvey, in his new yard at LSU's tiger habitat on Monday morning, Aug. 21, shortly after the 11-month-old male Siberian-Bengal mix arrived at LSU.

Putting on 174 pounds since August doesn't make Mike VII a fat cat -- "just a growing tiger" who is normal size for his age, LSU says.

The popular mascot was 179 pounds when he arrived at LSU in the summer. According to a post Monday on Mike's Facebook page, he now weighs in at 353.

In November, at 14 months old, Mike's weight was reported at about 270 pounds.

Tigers reach maturity between 4 and 5 years of age, according to the Facebook page, which is run by the LSU School of Veterinary Medicine.

Mike VII, formerly known as Harvey, turned 1 in September. The Bengal-Siberian mix was donated from the Wild at Heart Wildlife Center in Florida.
