Kitten I adopted 5 days ago crossed the rainbow bridge fter diarrhea and lethargy - I’m devastated and confused
I need to understand what happened. I adopted a 8/10 week old kitten on Saturday. He was at a vet clinic where he had been treated after being outside covered in bad fleas and diarreha. He had just gotten better.
The first two days he was active with soft stool but it was expected given the history. On Monday he had slightly softer stool but not yet full diarreha, he was energetic jumping around exploring but had lost a bit of weight from 700 grams he went to 670.
On Tuesday afternoon he started having stronger diarreha but was still exploring and seemed fine, the only thing I noticed other than the diarreha was that his third eyelid was showing so I texted the vet. She told me to check his gums they were light but not too pale. She told me that if I wanted I could bring him in on Thursday or if I was worried on Wednesday.
On Wednesday he started getting more tired and less curious so I called the clinic told them everything and set an appointment for the afternoon. He was cuddled by my family at lunch where he was starting to get lethargic. I got home to bring him in and found him dead.
I’m so MAD. I should have just brought him in but I trusted the vet that had him in care for three weeks to know better than me. I haven’t stopped crying since. I feel like he could have survived if only they had kept him in the clinic instead of adopting him out. I had cats all my life and nothing similar has ever happened we even found a 3 week old kitten and raised him perfectly my current cat is 14 so I should have known better that soft stool light diarreha was an emergency for him. I only had him for 5 days but loved him so much he wasn’t yet introduced to my cat directly but she would stare him out through a gate I had in front of his room. He loved playing and cuddling and loved his bed he was always on it despite the different options. He also had a Mickey Mouse on his side he was perfect, and I miss him.
I’m sorry for the rant I needed to vent and see if anyone went through something similar
