i'm so sorry... like what you said, it's hard to keep on caring for strays for they have been exposed to all those diseases already. you get attached to them but they have to go too soon. it breaks our hearts every time we lose one of them, but we can't stop now coz there are still a lot of them to help. maybe it is not our fate to save them but to assist them on their final days. it hurts but you did a good thing. although it's hard to understand it right now, it is their time to go and we have to move on. God Bless you!
