Since nobody has given the exact answer yet, here it is: Every single pet is unique in what it likes. This is because every time you present a consumable item to your pet it has a 50/50 chance of liking the item. After deciding whether it likes the food or not it saves that preference for the future. So the next time you show it that food it will remind you whether it liked it or not. More pet information can be found here: http://starbounder.org/Pets
Mine eats cooked fish, but try different things. I have a rabbit that will only eat steak so you never know what may turn their turkey.
What if you don't want a pet in your ship that makes you feel guilty for not feeding it? But yeah, I think it's randomized. Isn't it?
They said they may add a Pet Cage to remove starting pet for users who don't want it down the line. Or If you don't want a pet - you are free to use my mod http://community.playstarbound.com/resources/purchasable-pets.2854/ It removes the starting pet as well as lets you choose which starting pet you want. Sometimes its just better to be proactive and fix issues your self ( especially considering how easy it is to do it ) then just complain about everything.
I was about to jump in and say Cat Food. Until I saw everyone else's comments and thought whether a joking answer would be suitable.
Complaining builds a better game though. It's good to give feedback on both things you like and don't like. It's just complainers are often viewed in a darker light. Anyway, cool mod. I'll keep it in mind when I return to Starbound, but the Giraffe build is just too boring for me right now. I'm sure the upcoming update will be cool though. On topic, I lucked out with my pet and it turned out to love regular cooked meat you could get with any hunting weapon. I just used that to feed it.
Another question how many stars are there because i have a mod and i dont think it works[DOUBLEPOST=1439771112][/DOUBLEPOST]Types of stars
My snake hated coffee cake, but loves meat scraps? I just wanted to treat you nice you ungrateful serpent!
