Hi Airtia welcome to our community
And don't hasitate to ask away
The way to put your cat on pet food is to set breed off in the kittens menu.
The kitty will eat 50% less and doesn't breed.
Should you want to breed the kitty again after a while you can set breed on via the menu.
They need to recover from pet food though and after you have set breed on again it takes a week before they gain love again.
It is possible to make them instantly gain love after having them on pet food via the pet food recovery vitamin.
The permapet vitamin makes them a non reverable pet which does not eat and does not breed.
Permapetting a kitten can be done when it is fully grown up and this is when the kitten becomes 7 days old.
There is an interesting price difference between permapetting a kitten at the breedable age and when the kitty turns to old to breed 120+ days.
They have different vitamins for this.
I hope this helped!
