Help Mylo Get Better

This is Mylo . Mylo's owner left the country and left him behind sleeping rough outside his old house . We fed him , neutered him and got him back to good health . In part subsidized by Dublin Cats Aid . Mylo went to a new loving home and was settling in well with his new parents and 4 other cat brothers & Sisters . Unfortunately last week Mylo became very sick and has been to vet multiple times and is now having surgery to find out why he is sick . This is has been at the huge expense of his new parents . Can any of you cat lovers out there reach into your hearts and pockets and help us and Mylo out ?? thank you
