Oh wow. It sounds like little Kalani made a full course meal out of that plastic
the good thing is - it's coming up or out. The only thing I can think of that they'd do is an XRay but IF the pieces are still coming out - that has to be a good sign along with his appetite and having normal poops -
as long as he's acting OK you just may be in the clear but - Wow he does have a cast iron tummy
- this really could have caused some problems but it sounds like he's feeling pretty good - I'd be happy for that and see what the vet says regarding the next step if there
is a next step.
good luck girl !!
