Justin looked watching as Francine gained yellowish fur with spots, he himself started to get white fur, as the two changed. Snowy looked over, still worn out from giving birth. Justin tore off his pants and shirt, as Francine followed suit as the changes progressed further. Sally walked in and turned. "Oh dear god. DAD, cover up."
Justin turned, "Hey sweetheart. Sorry about that. It was irritating."
Fur spread on him as well as Francine who was nearing the completion of her change, her torso growing as a pair of legs grew out. Francine stretched as she grew the final mark of her being a chakat. Justin had already gained his pussy, while his nutts became internal, and breasts grew, his body stretching out to suit a chakat's size, forelegs grew out and touched down. The last change on him... I mean hir was the face, fur growing as a muzzle pushed forward and ears migrated up. When the two changes had finished, Justin resembled a black panther with a white mask over the face and Francine that of a serval.
Sally turned around, then looked at Snowy and hir kit then added two plus two, smiling. "Well, now we got more Kats." shi giggled. "How's Snowy?"
"Tired but ready to start work on the purrfect vaccination. Luckily you got enough blood from Justin before this." Shi walked off, going slow, having entrusted hir with hir newborn kit whom shi named Snowflake, combining hir and hir niece's names. Sally followed behind. "Things just got interesting." Shi giggled.
Snowy nodded. "I agree." Shi walked along as well as shi could.
