A month ago, my cat had a urinary blockage and needed a catheter. We followed all the vet’s advice, but he warned us it could happen again. Unfortunately, it did yesterday, and surgery was needed. We couldn’t afford it, so I had to make the heartbreaking decision to put him down. I know some might judge me, but I felt I had no choice. I’m just really sad and need to vent.
I’m so very sorry. My heart is breaking for you.
I am really sorry. You obviously loved your cat and did the best you could.
I am so sad for you. It really hurts and displaces you for a while, I know.
That is so devastating 
So sorry. No shame in making a tough choice when finances are tight. Let yourself grieve.
I had to do this exact thing 2 years ago. It was heartbreaking. I’m grieving with you.
Good of you to not let him suffer. You did the right thing.
This same thing happened with my cat too. It’s heartbreaking.
You put your cat before yourself, and that speaks volumes. He’s in a better place now.
I’m sorry. Same happened to us; making the decision was incredibly tough.
