Size of a litter for a carnivore with a high rate of death

So, I'm designing an alien race/civilisation of carnivore.

I was thinking of a very aggressive specie, who is both the alpha predator of his world and his own main cause of death.

Basically, a lot of them die all the time: reaching an adult age is not frequent, the adults often kill the kids, the adults kill each other very often, there is no hospital, and every period of reproduction ends up in a blood-bath when only one male and one female survive and succeed to reproduce.

Is it possible to each litter have only one baby?

Is there any carnivore species on earth who has only one baby per litter? How can I determine a realistic number of babies by litter to avoid the extinction of my specie? (I have the percentage of death for each of the previously listed cause of death)

Edit: a few stats: 10 years to be able to reproduce. Around half of the kids die before that. Each time there is a reproduction spread (once a year) there are between 1 and 3 deaths. The parent(s) will not be able to reproduce for 3 year if they raise kids. Parent can reproduce until 60 years, but only 10% will reach this age.
