Glad to hear that Broly made it through the surgery, and it sounds like he's doing better. He's definitely a trooper for overcoming all the stuff he's had to deal with -- and you too, of course, for taking care of him through it all.
It's easy to get lost in all the different colors urate can be, but I think off-white is the most normal one, so you're good there. If it stays that way, that's one less thing to worry about.
We just got back from visiting family in Homer and it was quite an "adventure" (euphemism) this time. Our car broke down in the middle of nowhere on the way down. First thing to go wrong was the engine overheating, so we managed to get it a little further along by stopping every few miles to let the engine cool down, but then it decided it was out of gas (we had half a tank) and wouldn't go at all, so we had to get towed the rest of the way, and then we had to have it towed all the way back to Anchorage ($$$) because there were no shops in Homer that weren't booked out for weeks. No rental cars available so we borrowed one from a friend (a very good friend, we owe him big time) to get me back home because I couldn't ride in the tow truck with my husband (can't climb up that high and not enough room in the cab for two people anyway, and not allowed to ride in the car while it's being towed.) So my husband rode home with the tow truck, got the car from our friend, and drove back to Homer to get me. Then we almost hit a moose on the way home (at least it was almost -- stopped just in time) and then almost got mixed up in a forest fire -- the fire trucks had traffic stopped and backed up for about 3 miles along the highway. Fortunately, we were one of the first in line, but too close to the smoke for comfort. If I had seen flames I would have freaked out, but it looked like they got it out before they let us move on. I don't like to think what else could have gone wrong on this trip. At least we made it home in one piece, just barely.
