Help Rasta Overcome Intestinal Obstruction

This beautiful boy was found running the streets, while looking for food, he must've ate a corncob. Found out after adopting him, he had a intestinal obstruction. He had emergency surgery and the corncob was discovered in his intestine. His vet bills were around $5000. His name is Rasta, he's 3 1/2, he's doing much better now and healing, any help is much appreciated. Thank you
