i accidentally kinda hit my cat a couple of woks ago. i didn't even know it til i got out of the car and saw him come from the other side limping. he walked several ft, sat down and let out one long yelp. i knew he was hurt but didn't look bad at all, so i left him alone. fast forward to the present...he's doing great, walking faster and is able to jump when he has to. a few days ago when he'd get in my lap, he had an overwhelming smell like he had been rolling in poop. he's a white cat, so i could quickly surmise he had not been doing that. when i picked him up one day, i noticed a red hole btwn his belly and bottom. i can only describe it like when u see a characters nose cut off in a movie and all they have is 2 nostril holes. when i told a friend about the smell and the hole, she said my cat had an infection.
