Odie Sick

My cat was sick on 9/24/2012, when I first noticed it was when Odie's bottom was red.  He had been chewing his hair out of his own body. I have no idea why he did this, but it looked painful to me. I start checking the internet and see what was wrong with him, but I could not find the right answer for it.  Next thing I went to the web and seach for the treatment for him. I took for his symptoms, and it looked like he had a hot spot, that why he chewed  his hair off.  I seached for the treatment and found two which will help him feel better.  One was for Hot Spot Relief and the other one was called Antimicrobial Wound Spray which will heals cuts, scrapes and abrasions, also kills bacteria.  I order both of the treatments online.  It did not take long before the treatments came to my house.  I started using it right away, first I used the Hot Sport Relief for 7 - 10 days, it impoved slowly, but it worked. Meanwhile when I was putting the treatment on Odie, I made him a head cover, so he can not chew his hair anymore.  Plus, I don't want him to eat the medicine. I want the medicine stay on his wound. Althought I know he will not get sick, because these treatment were clinically tested and veterinarian approved. It safe for the cat, even if he eat it.
