And I didn't know about Ham - I thought that https://en.wikipedia.org/wiki/Laika was the first space animal! Sure, I'd gladly post about Chester althought a cat doesn't fully support the idea of my profile :P Cats are friends though!
I invite you to read about chester on my profile then soon. :)
Laika was the first space animal, but didn't actually interact with the vessel.
C'mon, cats and dogs can get along just fine!
