Is the word animais the same in Brazilian and European Portuguese?

Yes

The word "animais" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In most Brazilian dialects, the final "s" is pronounced as a voiceless alveolar fricative [s] (like the "s" in "sun"). In Continental Portuguese, the final "s" is typically pronounced as a voiceless postalveolar fricative [ʃ] (like the "sh" in "show").
