Cat needing a home until Monday

Hi all. I found a stray tuxedo cat, and even though I normally don’t take strays, this was the friendliest cat I’ve ever met and I couldn’t walk away. A neighbor in the area I was working in told me that a family was evicted and just threw the cat out and left and he couldn’t take it because of his dogs. I’ve tried contacting a few shelters but unfortunately most are either closed or appointment only which can’t be scheduled until Monday. I already have 3 cats and can’t keep him, so I was hoping someone on here could pull through :( I’m not sure if it’s a boy or girl
