Why the next 48 hours matter for a treated cat
Even after initial vet care, the toxins affecting your 5 kg cat can linger in her system. The mold in compost produces substances that disrupt nerve function, and their effects may come in waves rather than fading steadily. What looks like recovery at first could still be followed by another round of symptoms if enough toxin remains circulating or gets reabsorbed from her digestive tract.
Watch for subtle changes in how she moves—a slight hesitation before jumping, or resting more than usual after brief activity. These can hint at returning muscle weakness before obvious tremors appear. The quiet room your vet recommended helps you spot these small shifts in behavior that might get missed in a busier space.
Four relapse signs that need immediate callback
While tremors and seizures are clear emergencies, earlier warnings include sudden dilation of her pupils in normal light or repeated lip-licking when not near food. You might notice her third eyelids (those pale membranes at the inner eye corners) rising more often, which cats show when nauseated or uneasy. Any return of the original vomiting or diarrhea means her gut is still irritated.
Less obvious but equally urgent is rapid breathing while resting—count her breaths per minute when she’s asleep (normal is under 30). If her sides hitch faster than that or with shallow motion, the toxins could be affecting her diaphragm control. Don’t wait for collapse; call your vet at the first hint of these.
How activity level predicts recovery
A cat who steadily resumes normal routines over 48 hours—jumping to favorite perches, grooming thoroughly, showing interest in play—is likely clearing the toxins well. But if she stays withdrawn, parks herself in one spot for hours, or only moves when prompted, her nervous system may still be struggling. Note whether she’s using the litter box normally; straining or avoiding it suggests lingering discomfort.
Hydration is another silent signpost. Gently pinch the skin at her shoulders—it should snap back instantly. Delayed retraction means she’s tipping toward dehydration, which complicates toxin clearance. If she’s refusing wet food, try dripping water on her paws to trigger licking, or offer ice chips to lick if she won’t approach her bowl.
When to ease restrictions
After two full days with no returning symptoms, you can gradually reintroduce normal household activity. Start by cracking the door of her recovery room so she can explore at her own pace. Avoid sudden loud noises or unfamiliar visitors for another day—her system will still be sensitive to stress hormones that might trigger a backslide.
Keep her diet bland (boiled chicken or vet-approved recovery food) for three more days to spare her digestive tract. Watch stools closely; any return to loose or oddly colored waste means pause the transition. Most cats fully bounce back within a week, but mention this incident at future vet visits—some toxins leave lasting sensitivities.
