I'm coming in really late on this one. Sorry. But noticed by your posts that this has happened a couple of times? We have seen several ratties choke over the years, and I have to disagree with others to some extent (sorry guys, don't hate...just want to give my advice based on my experience).
We have an older girl who has choked several times over the last couple of months too. She has advance respiratory problems and a life long heart condition. We simply cannot let her work it out, or I doubt she'd still be with us. Her nose is pretty plugged up all the time, so choking comes kind of easily and gets scary fast.
Anyway, my first bit of advice might be to ask if you can tell what Scotch was eating before he started choking? You might be suprised how many ratties choke on some of their favorite items. Let me tell you....pizza crust and soy milk..BAD combo.
Matter of fact, I've had a few ratties choke on pizza crust, until we started to let it dry out over night before giving it to them. It's just too doughy and they love it so much they scarf it down! Mashed potatoes or even cooked sweet potato can be pretty sticky and cause choking. Peanut Butter is a HUGE no no (yet many people still give it). It's super sticky and they can choke very easily on it.
As for what to do when they are choking....if you just leave them be, you risk the chance they will choke to death. There is the Rat Fling (noted in Debbie Duccommons booklet and on the Ratguide website), but that really should be used if they are no longer breathing.
If the rattie is still getting air, but either gasping, or doing the "this is hard to swallow" thing, where you can see their ears go back, and eyes close every time they try to swallow, I will gently rub their throats a little and see if that alone helps. It often does. If they are drooling, I will try to gently swab out their mouths. Of course, you have to be very careful not to push something down in further, so tweezers, sharp objects etc aren't really a good idea. We go with a q-tip, but swab out just the mouth.
If they look like they are ok, other than just trying to get something down (and this is hit or miss), I might offer them something "slimey" to eat. Canned peaches are pretty good, because it has slimey juice to help whatever else is in there slide down, yet can come back out quite easily if it causes more trouble. I've heard of vets trying a syringe load of water...but that's a hit or miss too....I've tried it when I was at the "do or die" point :sad3: It worked once, and didn't the other time...and came right back out.
I do still recommend at least rubbing their throat. Because the longer they go trying to sort it out themselves, the longer the risk they might not make it, or the stress can cause them respiratory problems. I had one boy that had a very scary bout of choking....the next day he was wheezing. We had to put him on Baytril as the choking stress threw him into a respiratory illness.
Hope that helps...and sorry to go against what others have said. But I got home from work JUST last night to find Sophie choking. I helped her and had her breathing normally within 5 minutes. Who knows how long she was choking before I got home. :sad3:
