Well that’s not true. It’s just a real bitch. As a welder, helium leak check is about the toughest damn QC to pass. Most welding QC has some reasonable margin for error during inspection, but the damn helium doesn’t care. You can have a beautiful weld with a tiny imperfection at the start or end and it’ll piss helium just as badly as an entirely scuffed bead.
A tip i learned with my most recent cat is getting the food and water up off the floor. Helps them swallow better. And the flatter the plate you give them their food on, the better. Cats can be extremely fussy over anything touching their whiskers, so anything you can do to help them with that they’ll appreciate.
