Unless Howie the cat was VERY hungry yeturday, I think Roxy ate his food when DH and his friends were "watching" her. Today she woke me up to go outside. She has NEVER done that before, she always waits until I wake up to go out. she had a really big poop, the last part of it was getting runny and then peed, and then kept squating like she was pooping, but nothing was coming out. Then after a while a few drops ran out and I called her inside so she wouldn't hurt herself squeezing so much. Later today DH called and said she had a complete diariah blowout and then some blood. Poor little girl! She was acting kind of strange all day - not playing with her toys and bugging me a lot more than usual. He said he noticed she was acting strange, but after she had the runny/watery poo she was much more like herself. Has anyone else seen or heard of dogs getting this sick from cat food? (She eats Chicken Soup and so does the cat.) Should I take her to the vet right away or wait a day?
