The past few days, Simba hasn’t been eating much of his kibble at all, so yesterday we tried giving him some wet food thinking maybe he was having problems with his teeth making him not want to crunch down on his kibble. He ate some wet food we’ve been using to give him his medication with, so I ran out to buy some cans of wet dog food to see if he’d eat more of that. He snarfed down 1/3 of a can, which seemed encouraging.
This morning, he didn’t want to even eat the wet dog food, and didn’t seem like he was feeling very well.
A lab not eating is a Serious Thing. Fortunately Simba’s vets (Riverbank Vet Clinic) are awesome and they were able to work us in this morning.
Some follow up x-rays showed what appeared to be thickening of the walls of his stomach and, like with the previous x-ray, his stomach appeared unusually dense on the radiograph. This time he hadn’t eaten anything, so it wasn’t full of food like it was a couple weeks ago.
The stomach (upper right of the ventral-dorsal image) is quite dense and the stomach walls look quite thickened. That likely reduces what his stomach can hold too.
Vet suggested giving people food (chicken and rice) to see if he’d eat that. When we got back home, I made up some chicken and rice which he ate (very encouraging), but still turning away from his kibble and the canned food.
So now, as long as he’s eating, we’ll do what we can to make sure he’s feeling ok and comfortable. At some point though (could be a week, maybe months, who knows) he’ll probably get to the point where he won’t want to eat again. Then it will be time for that last visit to the vet.
One of the exposure meters in my collection (a Radcal/MDH 1515) uses this Eveready #493 300V battery as bias voltage source for the ionization chamber used to measure x-ray exposure. The rest of the meter is powered by 4x2V rechargable lead acid batteries in a D cell form factor.
Looks like this battery was installed in December 2002. Last calibration date for the meter was 2003, so it was probably replaced when it was sent in for the previous calibration.
After 16 years of sitting on the shelf, the battery is pretty flat.
Let’s take the cardboard off and have a look at what’s inside.
There are 10 plastic wrapped packs, each 1.3 cm x 2.2 cm x 6.6 cm long, all connected in series. Each pack appears to have 20 individual cells coated in a waxy type material and wrapped in plastic to hold them all together. With 200 cells, that gives 1.5 V for each cell.
Looks like there’s been a bit of leakage while the battery sat on the shelf for the past 16 years.
Had to take Simba back to the vet a few days after their annual checkup. He’s been having a lot of issues with throwing up on an empty stomach the past few months. Having him on famotidine (Pepcid) has helped some, but if it’s more than 5 or 6 hours between meals, his little tummy gets upset and he ends up throwing up. Vet also suggested omeprazole (Prilosec), which we’ll probably switch him to to see if that helps more.
It’s tough to watch the poor little pup going through all that.
Lately he’s been eating pretty slowly, which is a little worrying, and there was more throwing up than usual yesterday. As all Lab owners know, any change in eating habits is a cause for concern. Fortunately I was able to get back in to the vet this morning to get him checked out again.
Simba had some upper abdomen tenderness when the vet checked him out, so some blood work and x-rays were done. Blood work indicated that Simba was anemic, which raised a concern about something going on with his spleen. There didn’t seem to be anything strikingly unusual on the x-rays. Liver and at least part of his spleen appeared normal, but that doesn’t mean there isn’t anything wrong. He also has some osteoarthritis going on in his thoracic spine area.
Vet recommended an ultrasound to help figure out more definitively what’s going on. At this point though, I think our focus will be to just make sure Simba is as comfortable as possible. I don’t want to subject him to a major surgery at his age. He’s still getting around fairly well, and as long as we don’t let too much time go between meals, he seems pretty normal.
I’m starting to accumulate a bit of a power supply collection now, it seems.
Haven’t looked inside it yet, but I did plug it in and turn it on. Made the satisfying “thunk” of a big linear transformer being energized, and the 6.3 VAC terminals were putting out about 6.5 VAC (unloaded), which seemed reasonable.
A quick look around the Internets yields hits on various audio forms, so seems like a popular piece of gear in those circles.
While I was scoping out the electronics, Connie was over in the books and found a copy of Practical Antenna Handbook by Joseph Carr, so that went into the cart as well. No such thing as too many antenna books, right?
