Kitty Girl was 11 months old and on 2-14, I had to have her put down. She was not acting right for about 3-4 weeks, we had her checked out and the initial diagnosis was upper respitory. Antibiotics were given and a Vitamin b shot..from that day she went downhill so fast. Her belly was so swollen and she had such a hard time moving around. She was so weak. I bought KMR and started forcefeedings. She just moaned and cried. I know I did the right thing and i was with her , holding her and talking to her until she was gone..BUT, I cannot help wondering...what in the world happened. She was an indoor cat and had been with me since a week old. She was abandoned and I bottle-fed her. She seemed so healthy and playful. I read that FIP is a devastating illness..but does it hit without any signs, like it hit her? I just can't seem to let this go and move on. I lost other animals before but this one has hit me so hard..I can't beleive it. I miss my girl so much, I am angry that she was robbed of such a long life...I thought we would have many happy years together...Maybe thats what my problem is and why it bothers me so much. Any advice?
