Is this normal? Do they hate me?😅 (kidding)

Why are they hissing? Is it a stage?

Will this make bottle feeding harder? Their mom abandoned them:(

**I looked up some more stuff and apparently they are just learning how to do it and also they don’t recognize my scent. (They’re eyes are barely open so they can’t see me yet.) they are still eating good 😅 only 3 of the 4 hiss. The other is just a fatty and wants food. lol I think I’m going to keep him for sure 💙

*there aren’t any rescues in my area. And the animal shelter here is known to euthanize healthy cats quite often. I’d rather not risk it. :(
