All animals are animate in Czech. (At least I can't think of any that isn't.)
And a few (non-living) things are also animate, notably "sněhulák" (snowman). Some masculine nouns can be treated as animate even though they're not, e.g. car brands to express endearment - "Mám nového Forda." instead of "Mám nový Ford.", also cell phone: "Ztratil jsem mobila." (I lost my cell phone.) is also possible colloquially besides the more correct "Ztratil jsem mobil."
