To preface, I want to know if I should be feeding him kitten food- because of his approximate age we were told, the vet said to feed him and my adult cat the same thing. The adoption center I got these two cats from had none of their paperwork right, and the microchip numbers weren’t right on the records either. Bingsu (on the right) says 8 months and Dennis (brown tabby on the left) says 1yr,8mo. When I registered them at the vet, he said that seemed right for Bingsu because he had lost all his baby teeth and his adult teeth were fully grown in, and that was the only way age can be told for cats. 2 weeks after his appointment I noticed he has no tiny bottom teeth which makes me think he is much younger?
