Hi there,
I'm so sorry to hear of the passing of your cat. We certainly don't expect to lose them so quickly after adoption but unfortunate things do happen, esp. to outdoor cats. If possible, could you keep your kitties indoors? The average lifespan of an outdoor cat is only 2 years, while the average lifespan of an indoor cat is 17 1/2 years. Pretty good odds in favor of keeping them indoors, huh? But, if conditions don't permit it, then know that An outdoor home is better than no home at all. Plus they'll get love and attention from you. They need you! Thank you for being there for them!

Blessings,
Mary
