Just realized, sims 4 cats and dogs can't breastfeed

I just started another new household a day ago to have me, my first sim, and my Rebecca Goth together. I got Buttons so far matched up and now has kittens, who look exactly like Buttons the mother. I just realized; they brand new newborns. So I should let them be with Buttons, but my Sims should not have to feed them unless needed. But, There is no breast feeding or bottle feeding for them. I suppose, since Buttons seems to be natural cat that's l hardy like feral kit. They should be okay, but they should be at least be breast feeding. Since breast feeding is normal and mother sims do, if not at launch, then at this point with all the pack additions to animal ranching and family life would at least open for the mothering cats and dogs as updates for them to do the same along side their superiors. the parenthood could be updated where bottle feeding a newborn kit applies to the parenting skill.
