Again, a cathedraticum is a fixed percentage of general collections. In the parish where I was business manager, it was 6% each month. So if the parish took in $10,000, it was $600. If it took in only $1,000, it was $60. It wasn't crippling; and if you had a bad month, the hit was correspondingly reduced.Bravo for breaking the oath of silence, and special bravo for the clever and useful idea.
Parishes get closed when they can't get the regular bills paid, or there are no longer enough priests, or (being cynical) they're merely struggling and the diocese wants the money it could get from selling the property. But if you're not sending in much cathedraticum, it typically just means the bishop is indifferent to you and your needs.
I would definitely talk to your pastor. He knows what accounts the collections go into. The safest option, in my experience, has been to directly pay for some items or service. Perhaps you pay the electric bill (or some part of it) this month. Or perhaps the sacristy needs new cruets. But again, talk to the pastor.
