Sorry Oliver has not been feeling well. I know exactally how you feel
worrying about him all the time. It's so scary when they are sick.
I would boil the white rice and add it to some boiled chicken breast.
Adding alittle chicken broth to entice him to eat just might do the trick.
If he likes this you can continue this for a couple of days and then start
adding some of his kibble to it. The food that he is on is high in protien.
32% is pretty high. There are many good quality kibbles on the market
today, Wellness and Natrual Balance are two.
Natural Balance Organic (Natural Chicken only protein in it) has 22% protein.
I have been using this along with boiled chicken and veggies for about 4yrs
with wonderful results. Buddy never misses a meal
I hope your Oliver feels better soon and likes the rice, chicken and broth
so he will start eating once again.
Good luck,
