Correct use of forms of haber?

Question

I am working on understanding/memorizing the forms of haber. Is the following nonsense text correct in its use of haber?

---

Hay un gato donde (present tense)

había un ratoncito pero (imperfect)

hubo un evento trágico. Así (preterit)

habrá un gato donde (future)

habría un ratoncito si no (conditional)

había habido un gato. (past perfect)

---

There is a cat where

there was a little mouse but

there was a tragic event. So

there will be a cat where

there would be a little mouse if

there hadn't been a cat.

Answer 1

I think the last one should translate as: "there had been a cat" or "there was a cat"

Había muchísima gente en la estación. (There were a lot of people in the station.) --Imperfect.

• Thanks for the reply! I was trying to say "if there had not been"... - schub Sep 24, 2009
