Toxicity to pets
Cholecalciferol is one of the most potent mouse and rat poisons on the market. When ingested in toxic amounts, cholecalciferol, or activated vitamin D3, can cause life-threatening elevations in blood calcium and left untreated can result in kidney failure. Common signs of poisoning may not be evident for 1-3 days, when the poison has already resulted in significant and potentially permanent damage to the body. Increased thirst and urination, weakness, lethargy, decreased appetite, and vomiting may be seen. Acute kidney failure usually develops 2-3 days after ingestion of this type of mouse and rat poison.
Unfortunately, cholecalciferol mouse and rat poison does not have an antidote and is one of the most challenging poisoning cases to treat as hospitalization, frequent laboratory monitoring, and expensive therapy is often required for a positive outcome.
Cholecalciferol has a very narrow margin of safety, which means that even small ingestion of this poison can result in severe clinical signs or death. Toxic ingestions must be treated quickly and appropriately to prevent kidney failure.

If you think your pet has eaten something potentially toxic, call Pet Poison Helpline or seek immediate veterinary treatment.
