Answer: I can make an inference that john wants to get rid of his pets.
Explanation: I can conclude this because the definition of inference is "a conclusion reached on the basis of evidence and reasoning." I can also make an inference on this because of evidence in the panel before John says "Other days, I wish I would've kept the receipts." The evidence is when Odie (The Dog) and Garfield (The Cat) ran right past john.
