Alright folks, let me walk you through my messy little journey figuring out what not to feed these furry roommates. See, last month my neighbor’s guinea pig got super sick after munching on avocado toast crumbs – yeah, seriously – so I went down this rabbit hole.

The Salad Disaster Phase
Started by tossing random veggies into their bowls like some kinda health nut. Carrot tops? Check. Iceberg lettuce? Double check. Big mistake. Came back later and found Pancake the guinea pig literally sitting in diarrhea. Turned out lettuce gives ’em the runs bad. Wiped cage floors for two days straight.
Snack Time Experiments
Got brave and tried sharing my fruits. Gave Mr. Whiskers (that’s the hamster) a juicy grape chunk – dude went nuts spinning in his wheel nonstop for hours. Next morning? Found him sleeping like the dead. Panicked, rushed to vet, paid $120 just to hear “hamsters can’t handle sugar crashes, genius.” Felt real stupid holding that receipt.
Here’s what absolutely wrecked their tummies:
-
Rabbit food pellets – Thought “hey same aisle at PetSmart!” Nope. Made Pancake swell up like furry balloon
Dairy anything – Tried that “cute hamster eating cheese” TikTok trend. Cue cottage-cheese-texture poop everywhere
Raw potatoes – Forgot they weren’t french fries. Guinea pigs turned into gas factories
Chocolate – Yeah I know, obvious. But my cousin snuck M&M pieces “as treat” and we almost had rodent funeral
Lightbulb Moment at Library
Finally dragged myself to pet nutrition section. Turns out their tiny guts can’t break down fats or sugars. Who knew? Flipped pages till my fingers cramped. Wrote notes on receipts because I forgot my notebook – classic. Key takeaways?
Guinea pigs: Can’t produce Vitamin C! Their bodies just… don’t. Need bell peppers daily.

Hamsters: Cheek pouches aren’t trash bins! Stuff rots if they hoard wet food.
The Emergency Kit
Now my fridge looks like survival bunker:
Timothy hay stacked like haybales
Freeze-dried mealworms in mason jars (hamsters go wild)
Bell pepper strips prepped Sunday nights

Emergency Critical Care powder (life-saver when Pancake stopped eating)
Huge lesson? “Natural” don’t mean safe. Rhubarb leaves nearly killed Pancake – apparently contains oxalic acid that wrecks kidneys. Would’ve never guessed.
