Timeline of My Cat’s Final Illness: What Could We Have Done Differently to Save Her?
Our 8-year-old cat, Momo, passed away on October 9, 2026. I’m sharing her medical timeline to understand whether there were opportunities for earlier diagnosis or treatment that might have changed the outcome.
** Friday, October 2 • Started vomiting 5–6 times and developed diarrhea. • She had a history of diarrhea while receiving oral steroids for asthma since Jun. 2026, so we initially suspected a medication-related problem.
**Monday, October 5 • Stopped eating and was taken to urgent care. • Temperature was 104°F. • Bloodwork showed low albumin (2.7) and high globulin (6.0). F***l testing and feline pancreatic lipase were normal. • Received subcutaneous fluids, anti-nausea medication (maropitant), vitamin B12, and Convenia (antibiotic injection). Mirtazapine was prescribed to stimulate appetite. • Her oral steroid treatment was discontinued in favor of inhaled fluticasone.
**Tuesday, October 6 • Developed multiple mouth lesions that appeared to be spreading. • Drooling and nausea worsened, and she remained unwilling to eat.
**Wednesday, October 7: Emergency hospitalization • Presented with a temperature of 106°F, severe drooling with blood-tinged saliva, multiple ulcers on her tongue and lips, and unequal pupils (anisocoria). • Bloodwork showed anemia, inflammatory changes, and low platelets, although platelet clumping complicated interpretation. Her albumin/globulin ratio was approximately 0.5. • Initial ultrasound screening (POCUS) showed no obvious abdominal or chest fluid. • Hospitalized for IV fluids, IV antibiotics (Unasyn), anti-nausea medications, antiviral treatment for suspected herpesvirus, pain management, and supportive care. • A nasogastric (NG) tube was placed because she could not eat.
**Thursday, October 8: Suspected FIP • Her fever temporarily improved but later returned. She remained unable to eat because of painful oral ulcers. • Eye examinations revealed right-sided uveitis and corneal changes. The ophthalmology consultation raised strong concern for dry-form FIP, with concern that neurological involvement might develop. • FIV testing was positive, although she had tested negative in 2019. • Treatment with GS-441524, an antiviral used for FIP, was started. Prednisolone acetate eye drops, pain medication, antibiotics, famciclovir, IV fluids, and NG tube feeding were continued. • Her prognosis was considered guarded. An esophagostomy feeding tube and transfer to a specialty hospital were discussed.
**Friday, October 9: Continued deterioration • She remained unable to eat independently, with persistent painful mouth ulcers and drooling. • Her fever returned, her eye abnormalities persisted, and her vision appeared potentially impaired. • A gallop heart rhythm developed overnight.
• We transferred her to another ER that could plant an E-tube to assist with her feeding in the afternoon. • Her PCR panel confirmed FIV and feline calicivirus, and the vets were highly suspicious of aplastic anemia, and her condition was not suitable for a surgery under sedation. Given how much pain she was in and how poor her prognosis was, they gently advised us to let her go.
Momo ultimately passed away later that day.
I'm struggling to understand how a seemingly healthy indoor cat deteriorated so dramatically in just a few days, and how she suddenly becomes FIV positive. I also keep wondering whether the outcome could have been different if we had acted sooner or pursued different treatments.
For those with veterinary experience or who have been through something similar:
At what point, if any, might earlier intervention have changed the outcome? I noticed since Jul. 2026, a very small wound on her nose had never healed.
Could the steroids for her asthma have contributed to her condition or worsened an underlying infection? Her asthma started in May. 2025, and we started her steroid treatment in Jun. 2026, completed 22x prednisolone and switched to dexamethasone (completed 10x then another 9x since her asthma was not suppressed), plus fluticasone. However, she would have diarrhea each time she took the pill (even 1/4 of the pill every two days).
Was there anything else we could realistically have tried to save her, or was her condition likely already beyond recovery by the time the severe symptoms appeared?
I'm not looking to blame anyone. I genuinely want to understand what happened and whether there was a window when we might have saved her.
