I lost my Gem on August 5th to fluid around her lungs. She had been diagnosed with gi lymphoma in early 2019- when she was 12 although I never had her biopsied because she was too small. Her only symptoms were weight loss-whether eating or not eating- she was not absorbing nutrients. Seemlngly this all started when she had 4 teeth pulled- but they hide things so well. I tried changing food and had tried for a long time since she was addicted to Science Diet- a food that when I adopted her in 2007 from the shelter was supposed to be good- she also got wet food- but if I knew what I know now- wet food would have been her main diet. I wonder every day- was that what caused this? What could I have done differently that would have changed the outcome. After her diagnosis- and one vet- only one- who said get her off the dry food- I gave her only wet- or wet with dry on it- I tried everything to get her to eat and gain her weight back. I wish I had known about this forum then, because I researched everything, but somehow missed important information. When she died I was so focused on her eating- the fact that she was eating alot- ahi una by tiki cat only- that that anything else would be serious escaped me. It was like I was in denial that she would ever die.When she started having breathing problems I thought it was a respiratory infection- which in itself is serious- I took her to vet thinking we'd come home with antibiotics. I had to stay outside when she was taken in -xrayed and they found the fluid around her lungs and body cavity. They didn't think she would survive the treatment- and I had to decide what to do then and there. Only 13 1/2 years old. The vet said think of quality and I always did which is why I never put her through chemo-knowing she hated the vet so much and the stress it caused her. So I had to decide on euthanasia, and they let me in. Before I could see her they gave her a sedative to prepare her and she died from it. The vet brought her to me, and it continues to be the worst and saddest day of my life.I can't get past the what ifs. She also had a slight heart murmer- how did that play into it even though they said it doesnt always mean anything, can't get past that she was eating, drinking, and jumped up on the couch with us the night before- it all meant she would be ok to me.This forum and being able to write- potentially let someone else read her symptoms and get information, help someone else helps me. I need to try to think about 13 1/2 years we had together and how much happiness that little face, curiousness, playfulness, love I felt, bond brought me instead. I hope I can get to that point for her.
