Missing treats

The last time I checked just a few days ago, this package was still full with crab meat cat treats. As of yesterday at the time where I had felt generous to give the furries their treats, I was quite apalled to discover that the contents had all gone missing.

All that's left on the 3-feet high shelf of the laundry room was an empty pack with a big, gaping hole. The hole was nicely traced up with little, tiny teeth marks and so far, there has only been one suspect who actually knew where the treats are kept.
ARGGGH!! FUUUUUDGUE.......!
