Dogs and Cat pregnancy

[Luthviana]

In my current run, I am only able to have one cat and one dog pregnant at a time. Not 100% sure if the same applies to livestock. All is well on the human front however.
I've tried getting one more than male of each species in case they are meant to be monogamous and no luck.

The number of dogs and cats on the map is capped by the number of wolves (and foxes maybe?) and rats, respectively. Pregnancies will only happen if the number of animals is below the cap. Turning up the wildlife slider allows more wolves/rats and therefore more dogs/cats.

Hmm... I thought that the total # of pets was capped by clan population and the # of (wild)predators was capped by prey ..
Meaning your pet could get pregnant if there are less than (cap #) of pets for your population.
I have had a Clan of 6 with both a pregnant dog & a pregnant cat (papa cat was sold before mama had kittens because he turned Senior). After the babies were born, no more pregnant pets until I had 10 Clansfolk. (Even though there was game everywhere) Then all of the adult female pets got pregnant in 2-3 days.
BOOM! Puppies & kittens climbing the walls! Hee hee
