Under the belief that feeding dogs and cats reflects the guardians family’s dietary habits, we evaluated the palatability of sliced smoked-dried bonito, sliced low-salt smoked-dried bonito, sliced smoked-dried bonito ’fermented’, sliced smoked-dried tuna, sliced low-salt smoked-dried tuna, a mixture of sliced dried chicken and sliced smoked-dried bonito, a mixture of sliced dried sardine and sliced smoked-dried bonito, and low-salt dried sardine for 100 dogs and 100 cats. Results indicated that 92–99 dogs and 89–93 cats voluntarily consumed each product. When these products were sprinkled on dog or cat food that the animals had never been fed, the ration of the new foods which the animals took was increased. Because of the high palatability of these evaluated products, which are preferred by dogs and cats, these dried treats are regarded as able to enrich the guardians’ life and satisfaction with companion animals.
