Nevadans can now contribute $1,000 to a 501(c)(3) corporation and receive a $50 gift card for any pet or cat at the Nevada Cat Rescue.
The company also offers discounts on cat food and veterinary care.
The $1 million contribution is in addition to $1.1 million in donations made so far.
The Las Vegas-based Cat Rescue is also celebrating its 10th anniversary.
“We are grateful for the generosity of the Nevada Community, and our dedicated volunteers,” Cat Rescue CEO and President John S. McBride said in a statement.
“It is also the largest gift ever to a Nevada charity.”
Nevada is the only state in the nation that offers its citizens a tax-deductible contribution to help offset the cost of vet bills and care for sick pets.
In the past two years, Cat Rescue has received more than $15 million in private donations, which the nonprofit uses to help pay for vet bills, veterinary supplies and other services for cats and kittens.
Nevada has also been hit hard by the opioid crisis, which has seen more than 200,000 people die from overdoses.
