No, I read the previous articles you posted. That'll work now for humans now who can live on a varied omnivorous diet, but not yet for carnivorous animals like cats and dogs (at least cats). Currently, the fake meats do not have the same nutrient profile as the real thing, e.g., they are missing certain essential fatty acids from meat/fish that carnivores require.
That's true of the soy-based imitation meats, but this isn't "fake meat" - it's the real thing, cultured from living mammal, bird and fish cells, with all the components of those cells. True, as LuckyR says, it would be more like baby veal than adult steer, but flavouring can be added - including fat and hormones, if you want them.
(By the way, have you read the ingredients on a can or bag of pet-food lately? Most of it is grains and animal "by-producs" - chicken beaks, fish meal. integuments and offal.
Also, as mentioned in that article, they need basal animal tissues - bovine fetal tissue and stem cells as mentioned in that article - to grow more animal tissues, how much of it is not clear.
They don't need
fetal tissue and FBS; these happen to be a convenient byproduct of current butchering practice; it is harvested as a matter of course in slaughterhouses and sold for research and many products besides cultured meat.
With specific cells - mainly muscle, of course - you get a lot of product from a very small original sample.
As for the animal, it can go on living its life as normal. In the future, it may therefore only be necessary to have a few animals that have been selected for their cells’ characteristics to choose for biopsies. However, the possibility exists to eliminate the farming (in the classical sense, for food) altogether (discussed later). ....
.... researchers have been working for a long time in creating serum-free medium formulations. The reason for this is because serum is notoriously variable from lot to lot, expensive, and can lead to mycoplasma or other contaminants. As a result, nearly all embryonic and induced pluripotent stem cell culture is performed serum-free.

and that was a year ago.
So the factory farming has become laboratory farming - rather like the Matrix but starring cows.
Even if that were so, the numbers would be reduced to a tiny fraction of what they are now. In fact, in vitro meat production could be compatible with humane dairy and egg farming.
