Pet's info: Cat | Siamese | Female | spayed | 4 lbs
Hi. I have female cat and her age is 7 months. 4 days ago she has been spayed. I noticed a bruise at her abdomen. Aafter 2 days of surgery the bruise spread to bigger area. I brought her to the same vets and dr said it is due to painkiller which causes blood thinning. The bleeding will stop for some time and he gave me vit c to give to my cat. But im really worried because the bruise seems to be bigger each day. Please dr. I need 2nd advice.

It is certainly concerning that Momote has significant abdominal bruising after her spay and that it has been getting larger. Some anti-inflammatory pain medications can increase a bleeding risk, but generally not to this extent. Possible causes of Momote's bleeding could be related to surgical complications with a bleeding vessel in or just under the skin, clotting disorders, or liver failure (the liver makes our blood clotting factors). If it has not yet been done, consider discussing coagulation testing to determine if Momote has appropriate clotting factors and platelets. I'm assuming that your vet gave vitamin K (not vitamin C), because this can promote the development of more clotting factors. Momote should be rechecked by her vet to reassess the bruising and perform any necessary testing.
