So we recently started on a PVC tree for the babies and I think they chewed on or ingested some of the tape or plastic on it. Roux had already been pooping non stop earlier last night but I think he's constipated. When I checked on Aspen this morning she had poop face on and also looked constipated. Should I be concerned if they ate plastic will it hurt them internally?c

I wouldn't think they would have eaten the plastic as they do spit out the outsides of mealworms.
What else did you feed them?

Have you checked for dehydration?

When in doubt take them to the vet, they could do x-rays to see if the did ingest the plastic.

For constipation or diarrhea we recommend feeding canned pumpkin (no spices).

Please keep us updated on your little ones.
