Better to leave at vet there for 1 to 2 day to avoid infection. When bring home just make sure it is clean and do not touch the wound area ur hand have more gem than u can think.
That is supplement out there which help wound cure faster but i can remember the name, u can get advice from the vet.
BTW do not bath ur cat for 2 week or 1 month i can't remember need to ask the vet.

BTW when operation i don't think u cat know anything most of them will put the cat to sleep to prevent any accident. When u cat wake up, the operation is already done plus and the wound is exactly very small only ><
Don't worry too much it will cure in 2 - 4 week time

Hi there Mariellasays,

Congratulations on having such a beauty like Torres.
I can see that you love her very much 

Well... before sending Torres for spaying, you must make sure that she is in good and excellent health meaning not sick.  Also please fast her the night before the operation.  Meaning no food or water before the operation.  This is very important as cats might vomit due to the anethesia given.  Since they are drowsy from the anethesia some cats might choke on their own vomit and this might kill them so please make sure no water and food for Torres 24 hours before the operation.

Usually, it depends on the vet where you will send her.  Most vets will keep the cats overnight to monitor them after the operation.  If the cat is responding well, the cat will be released the next day.  Make sure that Torres is caged for at least 1 week as we want to minimize the movement in order for the stiches not to come open.  Everyday clean the wound and if you like put some 'minyak gamat' on it.  This will help the wound to dry faster. 

After the operation, it would be advisable to give her wet food rather than kibbles.  Get a few tins of Science AD which is the best and nutritious food for pets who are sick or after an operation.  No need to give any supplement at all.

Good luck!
