I'll start by mentioning that he seems to be fine now.
He somehow found a small piece of duct tape and decided it looked like a good thing to eat for dessert. I noticed he was chewing something for an unusually long amount of time and then he started making a weird noise like he was trying to cough it up, and his ears went back. I picked him up and he was drooling a ton so I ended up doing the heimlich several times. I feel lucky that something sticky like tape was able to be dislodged and he seems to be ok. The little shit is going to the vet on Monday just to be sure because I'm not sure if he swallowed more of it that could create a blockage.
We all see this reminder a lot, but please take the time to learn the heimlich maneuver for your rabbit!
