cats again

[navi tasan]

A)
1-I have had four cats but they all died.
Could one use this even if one had the cats at the same time?

B) Are 2 and 3 correct?
2-I have had four cats. Three of them died. I still have one.
3-I have had four cats but three died and I have only one now.

Could one use this sentence if one didn't have the cats at the same time?
