Vitamin D supplements

Severity scale:

Vitamin D is something humans can benefit from, and since many of us do not get enough from sunlight alone, supplements are available. Unfortunately, high levels of Vitamin D cannot be excreted by our pets, and therefore accidental ingestion, especially in large amounts, can prove very dangerous. Vitamin D can be found in multivitamins, D2 or D3 tablets, capsules, or liquids, and can also be found in psoriasis creams. Psoriasis formulations can be deadly, while regular supplements can cause moderate symptoms depending on the amount ingested.

Toxic to: 
Dogs and Cats
Vitamin D2, D3, vitamin tablets or liquid, and psoriasis
Symptoms: 
Lack of appetite, increased thirst/urination, dehydration, vomiting, diarrhea, and abdominal pain.
