Normally cats recover quickly after the operation, and are back to normal activities and routine the next day.
Any swelling or redness is a sign that she’s not healing properly, call the vet immediately.. They are most unlikely to happen.

How is Callie!!!!!!??????
ABSOLUTELY WHAT OPUS SAID!
Your kitty really needs to be re-examined by the Vet who spayed her....there is NO charge ( or sure shouldn't be) for a post surgical check, something is not right, could be a hernia, infection or abscess even a fluid pocket...but Needs to be seen ASAP!!! Good luck and keep us posted
