"I have animals."
Translation:Ich habe Tiere.
If you take german in a school its way easier to memorize verbs like haben because the teachers teach us cool hints to learn material in limericks, songs, and hand motions. Maybe even more things. My teacher said that there is a limerick called EST TEN TEN. So, the first e means there is an e at the end, which is ich habe. The st means there is an st at the end, which is du hast. So on with t, en, t, en. Sometimes irregular verbs like lesen could throw you off. The conjugation for that is ich lese, du liest, er/sie/es liest, wir lesen, ihr lest, und sie(Formal)/sie(they) lesen. There are other verbs that are irregular too, but keep this in mind.
No. "hat" is for "he, she, it".
The form for "I" is "ich habe" - or, as Ungewitig_Wiht said, in colloquial German also "ich hab".
Totally correct would be to write it with an apostrophe to mark the omission: ich hab' - but that is rarely done nowadays. You will find it in old poems and some books though. Not unlike English do not -> don't or I will -> I'll.
In Plural, there are also four grammatical forms:
1) Nominative - die Tiere
-> Die Tiere sind grün. = The animals are green.
2) Genitive - der Tiere = of the animals
-> Die Farbe der Tiere ist grün. = The color of the animals is green.
3) Dative - (mit) den Tieren = (with) the animals
-> Ich spiele mit den Tieren = I play with the animals.
"Mit" = "with" (among many others) always requires dative. If you add "with", even GoogleTranslate will get it right.
4) Akkusative - die Tiere = the animals
-> Ich sehe die Tiere. = I see the animals.
Again, if you add "I see", GoogleTranslate will spit out the correct grammatical German forms.
