Screen door pushbutton latch - need just the latch plate, looking for suggestions

[techman41973]

I moved into a house with a screen door that has a pushbutton latch mechanism. Similar to this

I don't need the whole assembly, just the "strike plate" (which is missing) that catches the latch on the inside when the door closes. We have a cat and don't want it to push open the screen door and run outside. Can anyone tell me the formal name for this piece? I can't find it at Home Depot or Lowes. Pehaps someone has a suggestion.

They call it a latch strike and every hardware store or big box store has them on a bubble card down in Florida
