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.
Dogs, especially puppies, ingest a number of items that are not food, and intestinal blockage may occur.The main causes of intestinal blockage include the ingestion of bones, coins, toys, pebbles, buttons or beads.ogs, especially puppies, ingest a number of items that are not food, and intestinal blockage may occur.
