Hi! I am taking my 13 year old cat to the vet tomorrow, but I just have some concerns and questions. She has lost weight, even though she loves to eat and drink. She also has stopped cleaning herself because she constantly has diarrhea. She will just be walking by and fart loudly and have diarrhea. I have seen worms in her poo but that was only once. She now has a red, swollen bottom from the diarrhea as well as over licking it. She has licked off the fur around it as well as the bottom of her tail. She has dried poo stuck to her legs and bottom, and I have tried to give her a bath with no luck. I feel so bad for her. I am extremely embarrassed to take her to the vet because of how she looks, but she has got to go! I am so worried about her. Any suggestions about what might be wrong will be welcome. I am so worried because I am afraid they will suggest I put her down and I am not ready for her to go to Rainbow Bridge yet.
