Hi everyone, I’m looking for insight/advice on my cat’s situation. I’ll lay everything out clearly.

📍 Cat Info
Indoor cat
~15 lbs
No known major prior kidney diagnosis

📍 Initial Event
Developed vomiting and lethargy over a few days
Breath became very bad (likely uremic)
Was taken to vet and diagnosed with severe acute kidney injury (AKI)

📍 Initial Hospitalization (5 days on IV fluids)
Creatinine was initially off the charts (unreadable)
After IV treatment:
Creatinine dropped to ~8.1
Phosphorus improved
Clinically:
Became more alert
Started eating again
Peeing well

📍 Discharge (Friday)
Sent home because clinic does not hospitalize over weekends
Was NOT sent home with:
Anti-nausea meds
Phosphorus binder
SubQ fluids

📍 At Home (Weekend)
Initially did okay
Then:
Appetite decreased
Seemed nauseous (“wants to eat but hesitant”)
Slight bad breath returned
Still:
Peeing ✔️
Pooping ✔️
No vomiting ✔️

📍 Recheck Labs (After Discharge)
Creatinine rebounded to ~13.3
BUN ~123
Phosphorus ~11.6 (high)

📍 Second Hospitalization (Current)
Back on IV fluids
Now receiving:
Anti-nausea meds (2 types)
Acid reflux medication
Phosphorus management (though there was some confusion—phosphorus was high on labs but they mentioned giving phosphorus)

📍 Current Clinical Signs
Eating again (ate a full bowl when medicated)
Still peeing well
Pooped
Occasionally salivating after eating (likely nausea)
Was seen laying in litter box at vet
Otherwise:
Alert
Reactive
Still has personality (swatting, etc.)

📍 Key Concerns / Questions
Rebound in creatinine
Dropped significantly on IV, then shot back up after discharge
Is this typical for severe AKI?
Prognosis
Does a cat like this have a realistic chance of:
Stabilizing?
Living months/years with management?
Treatment approach
Does it sound like she just needs more time on IV fluids?
At what point do you decide it’s not working?
Phosphorus confusion
Lab showed high phosphorus (11.6)
Vet mentioned giving phosphorus without recheck
Is there a scenario where that makes sense?
Behavior vs labs mismatch
Labs are extremely high
But cat is still:
Eating
Peeing
Interactive
How common is that?
Next steps
Should we consider ultrasound?
Should we prepare for long-term subQ fluids?
