Food and such

So Grover has had loose stool, but today it was big and yellowish (like too much bone) with a little blood. I think the blood is from the size, but what bothers me more is that he pooped outside the box. The vet of course wants me to bring him in for full tests but I did that last year. Am I too spend 400 dollars a year to find out there is "nothing wrong"?

They loved the pieces of catfish. Not sure how good it is that they are eating cut up pieces of fish. Ranger is mad right now because the last two days have been quail, and he doesn't like it. I have not seen him eat today which is ground chicken. Our food came from Hare Today Gone Tomorrow. See ?

If Grover's stool is like this from too much bone then I need to think of a way to add boneless meat to just his diet because the rest of the stool in the box is fine.
