Hello. My kitten poppy of 8 months was spayed two days ago on Friday. Since I got her back I noticed her "voice" has changed. At first I thought maybe it was just the anaesthetic but her voice is still rather raspy when she meows. Just this morning she started having this heaving cough. She's done it a couple times so far but she's not vommitting just coughing really heavy. Then I'll go check on her and she stops when I pick her up. What could this be? Is she sick or could this still be a side effect of the surgery?
