Now it isn't likely Percé would have eaten the wood itself, though bugs and mice can cause indigestion and would be concerns here. Of course, we can also see nausea induced vomiting and anorexia in cats from bacterial or viral gastroenteritis, pancreatitis, parasites/protozoa infections, and general dietary indiscretion. And as cats are not well designed to be off food for long, we do have the additional risk of this leading to liver compromise (hepatic lipidosis),s o we do need to tread with care here.
Now since she sounds quite nausea but hasn't any of those other more urgent signs I asked about, we can try to ease her nausea just now. To do so, you can try her with an antacid. Common OTC pet safe options would be: Pepcid (More Info/Dose @http://www.petplace.com/article/drug-library/library/over-the-counter/famotidine-pepcid), or Tagamet (More Info/Dose Here @ http://www.petplace.com/article/drug-library/library/over-the-counter/cimetidine-hcl-tagamet). Whichever you choose, we’d give this 20 minutes before food to allow absorption. Of course, do double check with your vet if she has a known health issues or is on any medications you haven't mentioned. Though if you give this and she cannot keep it down due to nausea that is usually a red flag that we need to bypass her mouth with injectable anti-vomiting medication from her vet.
Afterwards, you can consider starting Percé on a easily digestible diet like boiled chicken, boiled white fish, scrambled eggs, or meat baby food (as long as its garlic/onion free). There are also OTC vet diets that can be used (ie Hill’s I/D or Royal Canin’s sensitivity) too. The aim of these diets is that they will be better tolerated/absorbed by the compromised gut. Therefore, it should get more nutrients in and result in less GI upset. As long as improvement is being seen, I usually advise continuing this until the signs are settled, and then weaning her slowly back to her normal diet.
Since dehydration is a risk here, we need to keep an eye on her hydration. To check that Percé isn't dehydrated, there are a few things you can test. Further to checking for gum moisture, do make sure she doesn’t have sunken eyes and that she doesn’t have a "skin tent" when you lift the skin. To see how to check these parameters for dehydration, you can find a good video HERE (http://www.ehow.com/video_12232503_dog-dehydrated.html). If you are seeing any signs of dehydration already, then that would be our cue to have her seen before this becomes an additional issue for her (especially as it is often dehydration that makes them feel unwell).
Overall, there are a wide range of agents could trigger what we are seeing. This doesn't sound like a poisoning with her lack of other signs but she sounds significantly nauseous still. Therefore, we’d want to start supportive care to settle her stomach. If she cannot keep that or water down at any point, appears dehydrated already, or doesn’t respond to the above within 12-24 hours (as we don't want this to linger); then we'd want to get her vet involved. They can assess her hydration, rule out fever, make sure there is nothing in her stomach that shouldn't be there or any sinister viruses present. Depending on their findings, her vet can treat her with injectable anti-nausea medication, appetite stimulants, fluids, +/- antibiotics to nip this in the bud for her.
