Our 6yr old cat "Dozmo" all the sudden has this foul smelling drool coming from his mouth and he looks like he is not feeling well at all. We cannot take him to the vet until we get paid. Until then I do not want something to happen to him. Someone told me to give him the penicillin I have and find out the right dosage for him. I don't want to cause more harm then good. Please give me some suggestions!
