Unfortunately it is not vet perscribed and it is people pennacillian. Before I get attacked by everyone, the reason she I gave her this was a matter of life and death. She had a sneeze that would not go away. It got extremely bad and after a few days she was wheezing and I could tell it went into her lungs. Unfortunately we are in the process of going bankrupt and have next to no money. I called my vet and he said it was probably and upper respitory illness by the sounds of it and it is now turning into pneumonia. He also said I have to get penecillian as soon as possible and that people pills would work if given the correct dosage. I told him I had some from a problem I had a few months ago, told him the name and said that would work. He also stated it was best to come in and see him but he couldn't do it for cheap or free even though he wanted too. He just opened the clinic with other doctors and they would not allow it. So I did what I had to do and now she is better. The only thing I am worried about is she is pregnant and didn't ask about this fact. I know it's our responsibility to take care of our pets but If you knew the hard time we were having this last couple months you would understand. We didn't for see these problems when we got our kitten and didn't think money would be a problem. Anyways, thats my explaination. I am sure some won't agree but now our pet will live so I believe I did the correct thing. You think the litter will be okay?
