I am writing this letter to personally thank you for the donation you recently made to our family pet, Sylvester.  Your generous gift is helping us to aid in the bill for Sylvester's surgery to plate his hind leg. His Vet, Dr. Gilbert has been so generous to us and Sylvester!

The support that has been given is so greatly appreciated, we could not have covered the cost of his surgery and anything additional. 

From the bottom of my heart, Thank you!
