Doing Melacha for a gentile or animal:[1]

All the Melachos of Ochel Nefesh were only permitted to be performed for the need of the eating of a Jew. It is however [Biblically] forbidden to perform Melacha of Ochel Nefesh for the sake of feeding a gentile or animal.[2] This applies even to animals that are dependent on oneself for their food, such as pets.[3] It is forbidden to perform to perform even Rabbinical Melacha on their behalf, such as to carry their food from a Reshus Hayachid to a Karmalis.[4]

Other opinions: Some Poskim rule it is permitted to perform Meleches Ochel Nefesh for the sake of animals. [Rebbe Akiva Beitza ibid; Ravaya; Razah; Raavad in Tamim Deim; See Bach 512]

[2] The reason: As the verse states “Hu Levado Yeiaseh Lachem” from which we learn that the Melacha may only be done for you and not for gentiles, for you and not for animals. [Admur ibid; Taz 512/1; Beitza ibid]
