I don’t understand why a 6 wk. old won’t eat solid food, unless he’s so congested that he can’t smell food which sometimes is the case. I don’t know what you mean by the oil, unless you mean adding it to his formula or food to help with constipation. At 6 wks. he should be using a litterbox by himself without stimulation I would think. Did the vet prescribe an antibiotic for his URI? Bless you for taking in these foster kittens, it’s a hard enough job when they are well, but seems they keep giving you sick ones. How disheartening. The oil helps soften the stool and get things moving, but he just may not have been eating much. You could add some solid food to the formula and make a gruel as he is probably lethargic because he is not getting enough nutrition. Please keep us posted on your kitten!
