Dear [recipient's name]:
Our hearts are broken as we let you know that our beloved cat Snickers died yesterday after struggling with various health problems over the past several months. We miss her terribly and treasure the time we had with her in our lives over the past 16 years. It seems like just yesterday that she was a mischievous little kitten who grew up to be queen of the house.
Thank you so much for caring and for being a support to us during this time of grieving.
