To find the probability that a sampled homeowner has more than 1 pet, we need to add up the number of homeowners with 2, 3, and 4 or more pets, and divide by the total number of homeowners. 
Number of homeowners with more than 1 pet = 8,318 + 5,567 + 921 = 14,806
P(Homeowner has more than 1 pet) = 14,806/31,156 ≈ 0.475 
Therefore, the correct answer is D.
