She is at the vet now getting hydrated with IV fluids. She'll be there at least until tomorrow.
I just got off the phone with my mom... I can hear the awful sadness in her voice. This was her baby from the day we got her over 14 years ago.
If her kidney functions don't improve within the next day, she won't be coming home.
Update:
Thank you for all the hugs and good thoughts.
Zoe had a seizure last night. My mom, dad and sisters are going to the vet tonight to say their good-byes. I can't be there so I asked my mom to give her a kiss for me.
This is hitting me harder than I expected (maybe because of the pregnancy hormones). I am just so sad that she doesn't ever get to come home again. She is the best cat, always so sweet and cuddly - her nickname is Mush. She gave us 14+ amazing years.
I am so sorry. This is the worst part about having a pet. I lost my family cat last year and it was so hard. Just know that you are doing the right thing for her by ending her suffering. Please FM me if you ever need to talk. Praying she goes peacefully.
