I spoke with the vet yesterday morning about Lily, but am not seeing improvement like she said we would. I'll try to make the story short - any advice is appreciated! Almost two weeks ago, Lily started squatting outside of the litter box, so I took her to her vet. They ran blood tests and urine culture, and found she had a UTI caused by ecoli, and also is in renal failure. (Her yearly checkup is in November and she checked out fine then!) She had no symptoms of renal failure, she is a big kitty with a very good appetite. She eats wet food with low phosphorus and low sodium anyway, but we will be gradually changing her diet to less protein to manage the renal failure. First to take care of the UTI, she was put on 14 days of liquid Clavamox with food (1 mL every 12 hours), which she tolerated well. Good appetite, and was obviously feeling better. I gave her FortiFlora probiotics with each midday meal, and she liked that a lot. On Day 12 (Friday), I gave her the evening Clavamox, and the next morning she ate a good breakfast but then threw it ALL up before I could give her the morning dose. I called our vet (this was Saturday morning) and she said to discontinue the Clavamox and give Lily 1/2 of a 10 mg Pepsid AC, which I did. She said hopefully Lily will feel better by Saturday night. All of Saturday, and again this morning (Sunday) Lily tries to eat and drink, but throws it all up, pretty violently, after about 10-15 minutes. It's been 24 hours since the first throw up yesterday morning. I've given her a little cat milk a couple of times, and she LOVED it and drank it up, and threw it up each time. She drinks water and throws it up, she drank a little gravy from her food yesterday, and threw that up. Today she doesn't want any gravy but is still trying to drink water. She also had a bout of diarrhea yesterday afternoon, poor little thing. I cleaned her up, and her next stool after that was a little firmer and also she didn't step in it, thank goodness. There has been no blood in her vomit or diarrhea, so far. Do you think it is a good plan to see how things go today (Sunday), and take her to the emergency hospital early Monday morning if she's not better? That will be 48 hours since the first throw up. Everything I read about Clavamox says cats eat again when you take them off it. Lily is eating, but can't keep it down. If things gets better today, that will save her a lot of stress not having to go to the animal hospital. She must be absorbing some water since it takes 10-15 mnutes to throw it up. Do you think that is a reasonable plan? Any other advice is welcomed, too! Thanks so much! Lily, when she was feeling better, just look at that sweet face!
