Questions & Answers about Когда дома заканчивается корм, я сразу иду в зоомагазин после работы.
Когда here means when/whenever, not just a one-time when.
In this sentence, it describes a regular situation:
- Когда дома заканчивается корм... = Whenever we run out of pet food at home...
If you used если, the meaning would shift more toward if:
- Если дома заканчивается корм... = If we run out of pet food at home...
That can be possible in some contexts, but когда is more natural if the speaker means this is the usual pattern: this happens, and then I do that.
Дома is a very common adverb meaning at home.
So:
- дома = at home
- домой = to home / homeward
- в доме = in the house/building
In this sentence:
- Когда дома заканчивается корм... = When the pet food runs out at home...
That sounds natural because the speaker is talking about the household situation, not literally about something being physically located inside a building.
