Well, the vet called and Osiris is a healthy boy! Fiv and FeLk were both negative!!!
He met some of the big kitties on an one-on-one supervised basis. Jules, all 18 lbs of him, is afraid of the kitten! Romeo fell in love and started to groom him. Phoenix doesn't know what to make of him!
He is bounding around the room right now. He somehow climbed into the big kitty litter box and actually used it! What a good boy! We need to get it out of the room though as it has clumping litter in it. We have a little box in here for him with regular litter in it.
