My cat Tiger has fleas. He lives at my dad's shop in the back where they build equipment. (He likes it there & we can't take him home.) We've tried to get rid of his flea problem by collars & medicine you put on the back of his neck. He got sick from the medicine & he tore the collar off. He hates water like most cats. I don't really know what to do. I have a very limited budget by the way. Any suggestions??
