Bless your family for rescuing little Bozo - I know that cats and kittens in industrial settings do not usually get lucky like Bozo did. I applaud the shelters in your areas however for not allowing adoptions during the holiday season as animals should not be gifts (since it is a commitment to be taken seriously after all). I am so sad that you lost both of your beautiful boys so unexpectedly and hope that you have or will be able to heal your hearts at least a little bit by helping out a few more needy kitties, as there are soooo many who could benefit from your love and care (and as you already know, they enrich our lives in return). I hope your vet will be able to ease your mind as to what took Bozo and Buster from you so suddenly - sadly it could be something they ingested in your neighborhood if they go outdoors (some people are nasty...). I wish you peace and know you will see your boys again one day.
