Mobile Cat Veterinarian

I am wondering if there is a mobile vet in Santa Barbara? My old 17 year old cat has lived out his life and its  sadly time to euthanize him. I called the Cat Doctors and they are booked for 2 weeks. Cat and Bird Clinic doesn’t have a vet available today. There is a mobile vet but they are not in the area today. I am hitting a brick wall. Does anyone know of a mobile vet, as I would prefer not having to traumatize my cat with a car ride, which he hates. Thank you for any help you can offer.
