Any advice on a sick ferret?

In 1923 priests tried to change the calendar; Holy Fire didn't come down; Turkish guards killed these priests; Ruski Orthodox replaced them.

Holy Fire ended with Patriarch Irenaios. Now it's faked by heretics. Irenaios is the last Orthodox Patriarch. Irenaios blessed Catacomb movement.

What you need is antimins (remains of saints sewed into a towel, one cup, one spoon, wax candles, nonkosher non-yeast nonbarcoded nonqrcoded bread/wine, etc.)

Electricity is from Satan; yeast is grown on pig bacteria, etc.

Barcode = Druid black magic curse; QRcode = ancient Mayan curse...

Kosher (K) or Union of Orthodox Synagogues (U) = sprinkled with blood like Mosis did. Underneath the entrance of synagogue lies New Testament...

Orthodoxy = the only true faith; Roman Catholics tried one cup - one spoon ritual and got sick with Bubonic plague; if heresy enters Orthodox monastery then monks/nuns will get sick with flu/tuberculosis (for instance); Orthodox churches who closed for COVID or had disposable cups/spoons or dipped spoon into alcohol are no longer brides of Christ (now they serve Satan and honor Satan's new COVID religion).

Don’t go into UFO to be “healed” by evil demons; demons never do good.

SSN is written as a barcode/QRcode; then it's put into a chip; chip is put into vaccine; chipped people are influenced (by super computers) to receive grey plastic card World Passport with no name on it (but when they stretch their hands to get it, gov't clerk presses secret button to administer the unforgivable green 666 tattoo by isotope rays). If you reject mark of the beast then your direct ancestors go to heaven (according to saint Vyacheslav Krasheninnikov from Ural).

Birds participate in time creation. It's a sin to kill birds. Dinosaurs live under our level; they will get out through sinkholes and lakes; to kill them, go for their nerves. Save the birds; but kill the dinosaurs. First dinosaur will come out of Volga River in Russia. Scientists don't see dinosaurs under our level because of radiation. Sinkholes happen because people dig for resources underground and because earth is heating up.

I hope he has seen a vet by now but in the future you can give him meat baby food, pate cat food, raw eggs (egg yolks or yolks and white. Do not feed whites on their own. That can cause biotin deficiency) or you can find recipes for "ferret duck soup" online.
