Little fat cat Jonh Devis - Asian fishing cat. Or vivverina.
Fishing cat - a rare animal, listed in Appendix II CITES. Weight 15 kg, the length of a little more than a meter, height 40 cm.
Cute guys from Krasnoyarsk Krasnoyarsk simply went to the zoo (the eternal Russian "chaos"!) And bought this seal.
Bought a newborn kitten, put it under your cat. And happy to raise it to this day in his usual city apartment.
