Ghost pets and ambrosia

I don't really remember whether they get resurrected as an adult or elder, but they should live for about as long as a normal adult/elder lives, like if pets take 20 days to age up/die then it will take her 20 days to age up/die. It will be as if she just turned into an adult/elder.

You can also just give them the age down treats to get them to the lifestage you want (it goes down to kitten/puppy). The treat can be found in the vending machine at the vet clinic.

On the topic of ghost pets. Does anyone know if i can get ghost kittens? If both cats are playable ghosts (i'm just guessing it's possible to have playable ghost animals (?)), can they still get kittens? I think the ghost pets are really awesome so it would be so cool to have a ghost kitten
