"It is a mouse."
Translation:É um camundongo.
They didn't - we use "rato" in Portugal for mouse (Mickey Mouse = Rato Mickey), with "ratazana" being "rat".
Rats are not ugly or unfriendly, though they have received a bad reputation. They are a larger rodent with a slender tail.(Though nothing in size to a say capybara.) Mice, or a mouse, are small rodents kept sometimes as pets or used as food for reptiles. Rats and mice alike are very intelligent.
