Pretty much. That's how I have 9. Occasionally hungry cats come to my garden for food. One of my best buddies passed away last year, I had built a cat house for him from a thing I got online, and I kept it there for other animals to use when the Winters come.
Recently a neighbour's cat came to my garden, whilst they were out of the house, and she had an abscess on her face, so I was able to take her to the emergency vets and they sorted her out (was a Saturday).
I don't know if it's just me being high, but I think animals can sense some shit. Was at a park with a buddy last Summer and I was kneeling down to read something on a rock, and a squirrel comes to me and is like, doing those hand gestures like it's asking me for something. My mate gave him some BBQ Hula Hoops, and the little dude was ecstatic.
I've been carrying water with me ever since that day, like, it would be really cool if I feed an animal water on the random.
I have a theory that initially a lot of these works were made for a laugh, like an old timey joke picture, and over time people kept adding meaning to them.
Like someone makes a rude and crude painting of a giant cock with eyes, makes people laugh, and a few thousand years later some bloke in a trilby goes "hmm, yes, it seems these people worshipped a penis god at this point in time. Also it clearly reads a prophecy, 'deez nuts'. Fascinating."
