how to make your cat poop

1. Notice that cat has not pooped for three days.
2. Make appointment at vet for tomorrow morning.
3. Realize that cat carrier is still dirty from the last time cat went to the vet with the same problem.
3. Go to pet store and purchase new cat carrier.
4. Put cat in new cat carrier to make sure he fits.

(Fortunately he pooped in the litter box and not in the carrier.)
