Can spaying a cat cause colitis? Or other complications?

I have a 5 month old female kitten who was spayed 2 weeks ago. She has developed colitis-like symptoms: semi-soft stool with blood and/or mucous. She strains to have a bowel movement several times a day, and if anything comes out, it’s usually bloody or has mucous.

She is otherwise healthy. Eating and drinking fine, playing and energetic. I am feeding her Science Diet – i/d which was prescribed by my vet for digestion issues.

I am taking her to the vet in a few hours, but am curious if anyone has experienced this with their cat after spaying.
Just to update… I took my kitten to the vet today and she prescribed the anti-biotic metronidazole for collitis which should clear up the blood/mucous.

She said the stress of the surgery sometimes causes collitis. She said to watch her for a few days, give her the meds (and catlax), and if it’s not cleared up in 5 days to take her back.

It does not sound like the spaying is the problem.She has some kind of intestinal problem. Believe it or not the doctors office may be very clean but his waiting room could be full of nasty germs and microbes. When I take my animals to the vet they are not allowed on the floor and I use an antibiotic hand cleaner before I get back in my car. I recently got a kitten who has this problem and found he could not have kitten chow. A few days on adult food and the six week kitten got better, Go figure..
