Recently caught a feral i"ve been feeding for a few months n got her spayed. She was pregnant when brought her in. After picking her up to drop her back n the woods she wouldnt leave carrier n still stays in it at home. Could this be just being scared or could she have developed a fever from surgery or rabies vac? Thank u.
You didn't say how many days it has been since her surgery. After being spayed, its not unusual for a cat to feel under the weather during recovery. It sounds to me like she's still not feeling well and knows she won't be able to defend herself in the wild.
I suggest you feed her for a few weeks but try to keep her in a separate area so she doesn't bond with you...unless you are willing to give her a home permanently.
It was great that you helped her by getting her spayed. TNR ( trap, neuter, return) is a popular and successful way of trying to control the feral cat population. More info at this link:
