Hello, I am sorry to hear about Moxy.Clumping cat litter can cause lots of irritation to the gastrointestinal tract. If she has eaten enough it can even lead to an intestinal impaction. Usually however those dogs are vomiting, have a tense painful belly and sometimes a fever. The cat stool she found in the box probably isn't helping her stomach either.Because she is still eating something and not vomiting we can try some things at home.To ease nausea and stomach irritation you can give her acid reducers either:1) Pepcid-ac (famotidine) at one 10mg tab per 20 to 40 pounds of body weight every 12 hours OR
2) Prilosec (omeprazole) at one 10mg tab per 20 to 40 pounds of body weight every 24 hours.Both are quite safe and can be used for several days if need be.
I do recommend you feed a bland diet of 1/2 boiled hamburger (or chicken), all fats and juices drained off mixed with 1/2 boiled, plain white rice. Feed several small meals a day.
I also recommend adding 2 tablespoons of canned pumpkin (not pie filing, just pumpkin) to each meal and feeding several small meals a day rather than one or two large meals as the more often she eats the more her gastrointestinal tract is stimulated to move.I also recommend adding water or low salt beef or chicken broth to meals. The better hydrated she is the better chance she has of passing the irritant.However if she is vomiting, is refusing to eat, has a tense painful belly or is running a fever (more than 104F) then she is likely beyond home care and needs emergency care this weekend.Let me know if you have further questions.
Thanks for all your help. One last thing, do you know around how long something like this would take to pass? How long should I wait before I seek vet attention? If she continues to eat and drink and does not vomit, is that a good sign this could fix itself? If not what is the treatment course for something like this? Thanks again!
