Oh no, how could you hate rats and mice,i've raised rats ever since I was little,and it makes me sad because they are not nasty at all unless your talking about sewer rats then yes they are nasty, but the kind that I keep are clean,smart,very friendly,and adorable,they just simply get a bad rep from movies.But as for an animal that I dont like there's not any but I dont like spiders and ticks,I actually have very bad dreams about spiders
