hispanics, immigrant ones, are notorious for dumping pets.
I’ve known white people to be just as rotten. I once had a girlfriend who dumped an older cat “she loved” in the woods because the woman had gotten pregnant and heard she could get toxiplasmosis from the cat litter. She said, oh, she’ll be fine, someone will take her in, and she can kill mice to eat.
I was cruel enough to tell her she probably painfully killed her trusting cat, and there were myriad things she could have done other than that.
