Here’s the Scoop:
How Zigrit’s first cold spiraled into a supplement storm
Why “maximum support” backfired in the most inconvenient way
Our litter box re-training journey (and how lickable treats saved the day)
What I learned about trusting her immune system and God’s design
A Sneeze Heard Round the House

Zigrit is our smallest cat. She’s got the tiniest frame, the most delicate paws and the kind of eyes that make you feel like she’s always five seconds away from asking to borrow your cardigan and a tissue.
So when she sneezed? I panicked.
It turned into more sneezes. Then some clear eye discharge. Then fatigue. She wasn’t dramatic about it, but I was.
Even though she’s a feisty girl who regularly schools her brothers in wrestling matches, my brain turned her into a fragile porcelain doll whose immune system clearly needed me to jump in and fix everything.
Enter: Supplement Overload
What followed was...a lot.
L-Lysine (at the max recommended dose, of course)
CBD oil for cats
Slippery elm for cats (to support her stomach in case the virus irritated it)
I was like a one-woman supplement dispensary with a heart full of worry. I just wanted her to feel better. She looked a little pitiful, and I couldn’t take it.
But after a few days of this ultra-supportive regimen, something new started happening.
And Then...Diarrhea
Yup.
Zigrit, who had never had any litter box issues before, suddenly started avoiding the box. I didn’t realize it at first, but she was having diarrhea...uncomfortable, probably painful and definitely anxiety-inducing for her. She began avoiding the litter boxes entirely.
And then she did something she had never done in her life: she urinated in a completely different room of the house.
Cue internal spiral: Was this a urinary tract infection? Was her cold turning into something worse? Had I somehow missed a symptom of a much more serious illness?
The Vet (and the Truth)

Off we went to the vet.
I brought all my detailed notes (because of course I did), described her symptoms and explained all the things I was giving her.
The vet listened patiently and kindly said something along the lines of: “It sounds like she has a mild cold...and the supplements may have been too much for her tiny system.”
Ah. Right.
They recommended:
Stopping everything except the L-Lysine
Reducing the dosage of the L-Lysine
So I did. And guess what? Within 24 hours, her diarrhea stopped. Her litter box avoidance started to resolve. And her cold? It ran its course, just like colds do.
Rebuilding Litter Box Confidence
But the trauma of her supplement-induced tummy issues didn’t magically disappear just because her symptoms stopped. She still felt unsure about using the litter box.
So we:
Switched to an open-top ModKat box (our old ones had either top or front entries, and the vet suggested that could be part of the hesitation)
Moved a box to a different room to avoid the old associations (this didn’t work great...Zigrit likes her routines)
Used lickable treats and positive reinforcement to help her feel safe again in the laundry room where the litter boxes normally are
At first, I just brought her into the room, placed her on the mat and gave her a treat. Then I started placing her in the litter box and using my most ridiculously sweet voice to tell her how good and brave she was. I mean truly over the top. Kindergarten teacher meets Broadway actress.
Eventually...she used the box. And I cried happy tears and gave her more lickable treats.
We kept this up for a few more days until she was confidently going on her own again.
A Valuable (and Humbling) Lesson
That whole experience taught me something I honestly needed to learn:
More is not always better.
Zigrit didn’t need me to flood her body with every immune booster I could find. She needed rest, basic support and for me to trust the beautiful, resilient immune system God gave her.
The next time she had a little cold, I gave a gentle boost, not a barrage. And it was so much better for both of us.
Takeaway Treats:
Tiny cats have tiny systems. Go gentle when adding supplements.
Diarrhea or litter box aversion during illness might be caused by the treatment, not the illness.
An open-top litter box can help cats feel safer and more confident.
Use treats and praise to rebuild positive associations with the litter box after a scare.
Trust the immune system God designed. Sometimes less is truly more.
