Yep, last week my kitten, Matilda, was really poorly and I made 3 trips to the vets in 2 days. I was due to go away early Friday morning and had previously arranged for someone to care for her, but she started getting poorly and was having seizures. On the Thursday evening I knew I had to take her again to the vets as she another seizure and the medication and injections didn't seem to be doing anything. When I got there the vet told me that Matilda had meningitis and that it would be kinder to put her to sleep, which I agreed.
Had I gone on my weekend away I know she wouldn't have survived the weekend, especially knowing how hot it has been. I am glad that I spent the last 48 hours holding her and syringe feeding her so that even though she was only little she knew that I loved her lots and lots.
I know that's a bit lame compared to a human, and I am sorry to hear of your loss. I'm sure you will get and give lots of support to your family x x x x
