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.
Rawhide dog chews are one of the most common pastimes of treats for dogs. Dogs love the taste of rawhide and owners love to give them something that they will enjoy.
