It is suspected that cats may be more likely to develop permethrin toxicity because they have different liver metabolic pathways to other species â in particular, they have a deficiency in the enzyme hepatic glucuronosyl transferase. Source(s): http://www.fabcats.org/owners/poisons/pe...
Re: Swallowed chunk of rawhide. In all honesty you need to contact your vet. Rawhides do cause blockages, especially in smaller dogs, because the pieces are too large to pass through the intestine. Contact your vet, and ask for some x rays. Cheapest, and most effiecient way to see if there is a blockage, how large the piece is, and if it is moving through.
Vomiting is one of the main symptoms of intestinal blockage, though the frequency, type of vomiting and consistency of the vomit vary based on the location of the blockage. Partial blockages cause intermittent vomiting that can include pieces of food.f you notice your dog is not passing regular bowel movements, an intestinal blockage may be to blame. A complete blockage prevents any stool from passing. With a partial blockage, small amounts of stool can pass, but you may notice your dog straining when he tries to go.
