Completely natural product - freeze-dried tuna and nothing but tuna. By type - fine powder, smell - whether roach, or dry food Rybkin. Weight almost no cost - beyond the imaginable (it generally is not spent, it seems to me). I bought out of necessity - a cat prescribed medicated feed, and he does not like. To somehow persuaded to eat a useful, but not tasty, it is necessary to embark on different shifts. This is - one of them. Cat is just really liked it, as many paws waving at me - Come on, say, do not wait. And feed useful for this case it went well, and even drops of smelly ate. But I know my cat, he quickly stale tasty things, so that has bought the next option.
