Just returned home from the vets .. Wasn't real impressed (new vet closer to new home) with what she did .. She looked at it, said yeah, it looks painful .. asked if she seemed agitated by it (she doesn't) and sent me on my way with Clindamycin and Metacam . I thought metacam was a big no no for cats and when I mentioned that to her, she said she had never heard of anything like that before and that she uses it all the time ? I'm supposed to keep an eye on the nipple for another 3-5 days and if it does not get better to take her back in .. She did not mention anything about it possibly being clogged .. When I asked if she had seen anything like that before she kinda scrounged up her mouth as if to say, nope, but instead said we see things all the time .. ? The vet visit did not put my mind at ease ..
