I am so sorry that things are piling up on you. The strays do seem to keep coming even though the money to do the ideal doesn't. You have given him food and kindness. That is a blessing. If it works to humanely trap him that would be great, but we don't get to save them all. The best we can do is the best we can do and if you break yourself down and burn out, no one wins. Take care of you.

It looked to me as if the cat in the picture may have had an abcess that opened and is draining. Ferals often hide when they are sick and the best you can do is know that the food and water he got from you eased him and may have given him strength to fight off the infection. He may have found another helping hand or he may have passed away. You gave him the mercy you could. Don't blame yourself for not being able to do it all. No one can. Treat yourself with the gentleness you would give the lost ones. Bless you for what you have done.
