IF injested will glitter harm a small animal?

Yes, ingesting glitter can harm a small animal. Glitter is made of small, reflective particles that can irritate the animal's digestive tract and cause health problems such as vomiting, diarrhea, and abdominal pain. In addition, glitter can also block the animal's intestines, leading to constipation and more serious health complications. If you think your small animal has ingested glitter, it is important to take them to the vet immediately.
