About a week ago, one of my feral tomcats started sneezing a lot. Now, one of my other feral tomcats is sneezing also. Mucous is clear, appetite is fine although they both look as though they have lost some weight but I'm attributing that to the fact that it is spring and the snow is gone and they can finally go where they want to. I haven't noticed any of the females doing any sneezing. Guess I'm just wondering if I'm just being to protective and this is like a cold or is it something I should be worried about?
