What is Rick favourite animal?

Please provide me with more context. Which Rick are you referring to?

* Rick Sanchez from Rick and Morty? He doesn't seem to have a favourite animal explicitly, but he does show a fondness for Snuffles (the dog) and Morty's pet, a rat.

* Rick Grimes from The Walking Dead? He might have a soft spot for dogs, as he was shown to be attached to his dog, Hershel.

Let me know who you're talking about, and I can provide a more accurate answer!
