I hear you. We lost two of our outside cats two years ago but gained one. We have quite a cat cemetery growing in our southeast corner of the lot. Our oldest is 15 and she came with the house. Three inside cats and three outside cats so far this year. We have two that like to stop by for food and water but the resident outside male doesn't let them stay long; he reminds them if they stay they get fixed. That drives most of them off.
Well we have a new outside cat. A male, stripped tabby, with very short hair. He has been hanging around since spring getting braver every week. About a month ago we were able to touch him and he is now demanding his food every morning. Sunday he disappeared and came back late Monday pretty beat up, bleeding and not to spry. Thursday we took him to the vet and the vet took him to surgery. He is now neutered and his leg is all stitched up. I picked him up this afternoon and he is back recovering.
We are calling him Peach. Now we see if he stays around or moves on to greener pastures.
