Breeding

Starting in Petz 3, the player can breed their Petz to obtain new Puppyz and Kittenz with features of both parents.

Breeding
Aphrodisiac items.

Pregnancy
A Petz pregnancy lasts two or three days.

Stuck Pregnancy
Stuck pregnancy happens when the computer's date and time is adjusted backwards.

Newborns and Infants
Mother Petz will panic when held by the player and will ignore the lock on the Supply Case if they want to leave.

In Petz 4, Playscene Hosts will not enter the playscene while a mother and her child are present.

Petz 5

Inbreeding
Inbreeding occurs when two Petz with overlapping Petz in their Family Tree are bred. This does not have a negative in-game impact but does increase the Pet's  file size significantly.

The game distinguishes between two  files with identical names, i.e. a family tree containing two completely different Catz named Tiger will not falsely be flagged as inbred.
