I used to have 12 cats, all very much loved and very well cared for. One by one they got too ill to do anything more for so, one by one I had to have them put down. So I guess if I had to have Falcon put down (if there was no other way) I would.. It does affect you though very much. (I think of them all very often.) It certainly doesn't get any easier. However, no matter how much you miss that individual pet (whatever it is) you will no doubt get another, may be the same breed, colour or whatever but compeltely different but you'll love it just the same.
