Yes. A barren cow (one that is open, or not pregnant) is able to come into heat or estrus.
No, the cow will not go into estrus after she becomes pregnant.
Estrus is the time in a female cats reproductive cycle which the female cat is receptive to the male cat. According to the question posted the cat had been spayed. If the cat has really been spayed it cannot come into estrus. If it has not actually been spayed and you just think it has, then it could come into estrus, but this is not dangerous (except she may get pregnant). Either way she will not die, or at least not of that!
It is not illegal to kill a bull.
