All Breed Companion
Animal Rescue

Meet Riddler, a big, handsome hunk of a cat with the sweetest, gentlest soul. Despite his mysterious name, there’s really no puzzle to solve here. Riddler simply wants a cozy place to land, humans to call his own, and all the love and affection he’s been waiting for.

Riddler is FIV positive, but those three letters are just one tiny piece of who he is. FIV+ cats can live long, happy lives, and what really defines Riddler is his gentle nature and ridiculously lovable personality. If you’re ready to give this professional lovebug the home he’s been waiting for, Riddler just might be the perfect boy for you.
