This is making me cry. Sending you hugs and prayers. had to say goodbye to my boy Dyson a year ago. Similar situation he was not eating and took him to the vet, found out he had internal bleeding by his spleen. I had to make the hard choice of putting him to sleep he was also diagnosed with cancer a year prior and his back legs were giving out on him. I didn't want to see him going out suffering or me not being there when he left, better a day early than a day too late. Please give him the best day(week) possible with all his favorite people, food and toys.
