Wouldn’t {Hoch vIghro’ luleghlu’} be “Someone sees each cat”?
Depends on whether Hoch vIghro' each cat is
considered singular or plural. This has been discussed before, but
I don't remember the conclusion. If it's plural, it's as you say.
If it's singular, the sentence needs to be Hoch vIghro'
leghlu' each cat is seen.
