I legit didn't even think about that tho

I thought the muskdeer died?

sand cat doesnt rlly give much to the plot , they were just there to be there lmao

No, if you read all the available chapters then you can find that the musk hasn't died yet. He got attacked then rescued by the humans and when he got back to the sanctuary, he found 2 baby leopards (a boy and a girl) who reminds him of that grown up leapard and decided to raise them. He then encountered the black lion who told him to move to another territory and when the leopard smell the black lion, he realizes its that musk and found him. They're still not together tho. The leopard is with the black lion.

... He's a serval....? and the other kids he adopted are servals too...?

Whoops sorry. I forgot the name of their species and thought that they were leopards instead...
