Good luck, Cara, you are trying so hard. We're pulling for you.
The soft poops seem to indicate the propulsid is working and fiber would firm the poops up.
If she is eating on her own you may be able to hold off handfeeding. If you can avoid stressing heart pigs, it is better.
Simethicone might be useful to try - Judi Lainer uses "0.15cc, give or take a bit (its 1/2 the low end infant dose), and I use it 2x per day."
And Beano is also helpful. I would use 2 to 3 drops of Beano twice a day til, her weight reduces.
See if your vet has portable oxygen tanks you can borrow/rent. Oxygen can really help get heart pigs over humps.
If the weight is fluid the vet might want to up the Lasix temporarily.
It is so tricky treating these guys for heart since there is nothing written. Forces them to be true guinea pigs.
Beano is okay to give at the same time. It basically just makes it easier to digest gassy stuff. Enzymes to aid digestion, maybe? I know it really did the trick for one of mine with a chronic gassy tummy AND motility problems.
Simethicone(sp?) is an infant gas remedy that works in the intestine.
Since her weight is returning to normal - I would start supplementing by handfeeding just to make sure she doesn't start losing weight.
You might have to separate her just for access to veggies but I wouldn't want to separate her all the time - too stressful.
Also how long does it take for the propulsid to remove the extra food/gas? It's been a day now. I am so worried I am going to lose her. SHe can't eat much and I'm worried about forceing the critical care into her. I haven't given her anymore since lunch. I held her while she ate the lettuce. Then I took the other three girls out and let just Zipper in the cage to eat. She wouldn't eat anymore. Should I take her back to the vet tomorrow?
2 to 3 drops beano in her mouth. The Reglan usually works in a few hours - not sure about the propulsid.
No, you shouldn't force her to eat if her stomach is full of gas - you could try gently massaging her tummy.
The beano dispells the drops right out of the bottle.
