I have a sick cat on my porch he has wondered up here yesterday. Can someone pick him up he really needs help. Or do I have to call on Monday?

Call Monday and report it.

Instead of letting a sick animal languish for days, perhaps contacting some vet clinics would be a better alternative. If the cat is feral, they might waive charges. If you are charged, you may try contacting the animal shelter to see if they can extend some assistance.

Someone should be on call but not sure.
