Rats can be very ferocious at times.
My feelings about rats are that they are treated very cruelly and killed because sometimes they are considered pests. I know when I say this most people will agree with me. There are the kinds of rats that need to be exterminated like non-domestic, disease caring rats, and rats that bite for no considerable reason. Domestic rats are also very prone to tumors. My rat Lucy that I told you about died last year from a tumor.
