the vet recommended it for my cats' teeth and i asked him if there was anything that was of a better quality and he said that it was fine, but isn't it actually bad for them because of all the fillers and by-products?

I started having this really sharp pain on the left side of my chest extending to the middle part of my chest. I can't seem to take a full breath and it seems to make it easier to catch my breath if I raise my arms above my head.

weird part is that this started hurting Saturday about noon and lasted all day (nonstop). I woke up Sunday with the pain mostly gone and everything seemed fine. I was even able to go to play basketball yesterday without any discomfort. Everything was great until this morning (Tuesday) on my way to work it came back and seems even worse as it hurts further towards the right side of my chest now. It hurts much worse if I am standing and the pain level seems to stay about the same level. I just had a physical about 2 months ago and nothing came back irregular.
