Pet's info: Cat | Domestic Shorthair | Male | neutered | 4 months and 26 days old | 5.5 lbs
Hello. My cat got neutered about 10 hours ago. His face is slightly swollen so I gave him 3 mg of Benadryl, and that was about an hour ago. His face is still swollen and his gums are pale but his nose is pink. He is also acting very lethargic and sleeping but I figured that's just because of the anesthesia. Should I take him to a emergency vet?
