Record Keeping: The Spreadsheet That Does More Than You'd Think

For a long time, we didn't track anything. With one or two snakes, feeding day just sort of happens, you remember it without trying, nothing about it feels like it needs writing down. That changed the moment we had four snakes at once for the first time, when baby Bajsa and Albi arrived alongside Hoggy and our ball python Marvin.

Bajsa and Albi were hatchlings, which meant they needed feeding far more often than Hoggy and Marvin did, so suddenly we had two different schedules running at once instead of one. And this is where it went wrong in a very ordinary, very human way. Every week we'd end up discussing when we'd last fed the babies, and every time, it felt like it hadn't been that long. Except it had. Life gets in the way, a few days blur together, and "not that long ago" turns out to mean something different from what the calendar says.

So I started keeping notes on my phone, just the date of the last feeding. That alone was enough to catch how much time had actually passed and get us back on schedule. From there it grew naturally: I added weights next, then shed dates, then everything in between. Once it became clear this was actually something we needed to take seriously, it moved into a proper spreadsheet, one place with everything in it. Every new snake we bring in just gets its own column added to the sheet, same as the rest.

Feeding day is the backbone of it now. Most of our snakes are on a weekly schedule, smaller ones every four to six days, and every single feeding gets a line: the date, the prey size, whether they took it clean. But the more useful part isn't the routine entries, it's the flags. Did they seem blue or in shed. Did they refuse. Did they regurgitate. Did the poop look off in any way. None of these things mean much in isolation, a single refused meal or one strange-looking poop usually isn't a big deal on its own. But three of them showing up over two weeks, sitting right there in the same row you can scroll through, tells a completely different story.

Weight works the same way. We log every weigh-in, and the number by itself isn't the point, the trend is. A snake steadily gaining is one story. A snake plateauing is another. A snake quietly losing weight over a few weigh-ins while still eating fine is the story that's easy to miss without a written record, and the one that matters most to catch early. That's exactly how we first noticed something was wrong with Julija, before it showed up any other way. The weight log said something before anything else did.

With a big clutch of hatchlings, there's just no way to hold every detail in your head, and honestly, you don't need to for the easy ones. A baby that takes a pinky straight off the tongs every single time isn't the one you need to worry about remembering. It's the ones that don't feed so well where every little detail actually earns its place in the log. Did it strike at the prey, or take it slowly and reluctantly off the tongs? Did it ignore the pinky at first and only eat it later, on its own, once we left the box alone? Did it show interest, smell around the prey, and then just not follow through? Each of those is a different pattern, and if you're only relying on memory, they blur together fast, especially across a whole clutch of babies at once.

For the ones that wouldn't take a plain pinky at all, we log exactly what we tried and in what order: did we scent it, and with what. Did we switch to fish, and if so, which kind. It sounds like a lot of detail for something as small as a feeding attempt, but a few weeks in, trying to remember whether a specific baby responded to any scent or a particular fish last time, you genuinely won't recall without checking. The log remembers so we don't have to.

This same closer attention applies to any snake that's new to our collection, not just hatchlings. Anything freshly acquired, or still in quarantine, gets watched and logged more carefully than the rest of our animals. With snakes we've had for a while, healthy, established, eating reliably, we already know their normal. We know what a typical feeding looks like for them and what would actually be a red flag. With a new snake, we don't have that baseline yet, so the record is how we build one. It's the only way to actually learn an individual animal's pattern instead of assuming it matches everyone else's.

It would be easy to let a habit like this slide once the original problem, forgetting feeding days, was solved. We haven't, and the reason is that it kept paying off in ways we didn't expect at first: catching a weight trend early, remembering exactly what worked with a picky hatchling, having an actual answer instead of a guess when something seems off.

It also just scales better than memory does. One or two snakes, you can manage in your head. A breeding season, a clutch of hatchlings, and a growing group of adults on top of that, and memory alone stops being enough. The spreadsheet doesn't need to be fancy to fix this. Ours is really just dates, numbers, and short notes, nothing complicated. What makes it valuable isn't the format, it's that it's actually kept up.

When a baby goes to a new home, it doesn't leave with just the snake. We put together a small spreadsheet for the new owner too: the last ten feedings, with dates, prey size, where the mice came from (sometimes a snake gets picky and will only reliably eat from one specific seller, which is honestly worth its own post at some point), and whether they shed during any of those feedings. We also mark the overall feeding count so far, and leave empty rows underneath for the new owner to keep going themselves.

We do this on purpose, not just as a nice extra. Most new owners haven't thought about record keeping yet, there's no reason they would have, and if we didn't hand them a starting point, plenty of them probably never would. Giving them a sheet that's already half filled out makes it easy to just continue the habit instead of starting one from nothing. It's a small thing to include, but it's one we think matters, since we know firsthand what a difference it makes once you actually need to look back.

If there's one habit from this whole hobby worth stealing, it's this one. It won't feel useful on any single ordinary day. It'll feel essential the one day something isn't ordinary.
