Don't get fooled by this. The huge leafs make the cat look smaller than it actually is. Wikipedia mentions a body length between 35 to 48 cm (14 to 19 in), with a 15 to 30 cm (5.9 to 11.8 in) tail. Which is close to the size of an average house cat at 46 cm (18 in) length.
I'm assuming there is some reason why it would be a terrible decision to get one as a pet.
The section of this video starting around 0:48 looks like 3d animation to me. Am i wrong? Is it possible they would fake some of this footage?
This reminds me of the House Hippo commercial
"They feed mainly on rodents and birds, but may also hunt lizards, frogs, and insects."
