Jill,
I haven't posted here in awhile, since my Gracie went OTJ, but your story hit home with me. I was really sorry to read about Charlie and hope you're hanging in there. On August 28th, I lost my beautiful Tuxedo girl, Samantha and her circumstances were very similar. Now she was 18 and had problems, but for the most part she was doing great, playing and eating. The week before I noticed she was breathing heavier than normal, and brought her to the ER. She had fluid in her lungs, and they determined she had HCM. She was on fluids for Kidney issues, so they assumed that was the issue. That night in the ER, I noticed she was shivering, probably twitching slightly and asked about it. The didn't think it was anything. I took her home that Friday and she seemed much better, but unfortunately by Tuesday she was weaker in the back legs and didn't move around much, practically laying on her food and water bowls. Her breathing was also labored. We took her back to the ER and her heart and everything else was fine, no fluid. The doctor said she was probably just sore from her arthritis and sent us back home with some bubrenorphine. At about 5:30 that night, I gave her half a dose of that, and soon after she couldn't walk at all and vomited. Assuming it was the pain killer, we didn't panic, but at 5:30am the next morning, she wasn't better and vomited again. This time, she was catatonic. Her jaw was locked shut and she wasn't moving. At the ER, she didn't improve at all and we had to let her go.
Like you, I was initially confused about what had happened, but thinking back to the first sign of trouble, the twitching I noticed was the key. She had had a minor stroke, but continued to get worse until the big one hit a few days later. I was mad that she had spent so much time at the ER and nobody realized what was happening, but the reality is, they couldn't have done anything anyway. She would have spent her last days in the hospital instead of with me.
I'm sorry to come into your thread for Charlie and focus on Samantha, but their stories were very similar, and they looked very similar. In the end, I guess we'll both have questions, but it seems like we did everything within our power to do right by them. Sometimes, bad things just happen and there is nothing that can be done. They were family, and having an empty spot in our hearts and homes is life altering. We just need to get used to the new normal without them.
This is Samantha's memorial..
