I had 4 who developed fip within 4 months
I had 4 who developed fip within 4 months. All different. The first had chronic diarrhea from a few weeks old (likely feline corona virus) and was underweight, dry brittle fur util he developed a wobble and lethargy at 4 months old when he was diagnosed. He started to recover after 24 hours of treatment! The second was coughing for 4 days, nothing else. He was 16 months. Got a little weaker and struggled to jump on tables etc and took 2 weeks to improve even though he showed less illness.
The 3rd had bladder issues so was treated for that until it was realised he had fip too and the vet advised to pts (happy for the other 2 getting treatment). The 4th was not gaining weight for 8 weeks, 3 months to 5 months, got tested several times and was always negative until one day he was so thin it was decided to treat him anyway. He was so weak he had a massive reaction to sedation and was paralysed.
He wasn't expected to last the night. He had his first pill at 9pm and the next morning he was screaming for food!! All are fully recovered and healthy.
