We have a ball who is maybe 2.5 yrs old. He has always been a good eater, typically eating 1-3 small rats per week. We increased the size of rat and he did fine with it through several feedings. But it has been almost 4 weeks now and he hasn't eaten. We put one in every week and after 24 hrs he hasn't touched it. Usually he eats within the hour. Just keep offering or is there something else I should look for?
