WHAT a purrrrrrfectly big kitty cat.

Meet 10-monthold Keera, a 51-pound mountain lion who recently paid a visit to The Post along with Animal Planet’s Dave Salmoni, a professional big-cat handler and the host of “After the Attack” (tonight at 9).

Keera, who eats about 6 pounds of meat a day, was born at a wildlife sanctuary in Florida and lives there with her parents, Sierra, a 110-pound female and Junior, who at almost 150 pounds is freakishly large for a mountain lion.

On “Af ter the Attack,” Salmoni – who has been bitten, scratched and clawed several times in his career – meets with people who have survived deadly confrontations with wild animals.

Salmoni is helped by a team of animal and behavioral experts, who investigate the stories behind each attack and try to aid the survivors through the healing process.
