: Is it possible for squirrels to climb down the outside vent, and come out in the toilet?: I have had 2 drown in toilet the past week. This seems unusual, but its only explanation I can think of.YES it happens-get someone to put wire over the vents before one gets lodged and blocks up plumbing. The most nauseating drain job Ive ever had was clearing a dead squirrel from vent line.
