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.
Really large doses of parsley given daily could be toxic to a dog's liver. So, it's not a good idea to be giving massive amounts daily. But, a little bit to flavor a treat is fine. Peaches: Mostly Safe: Peaches are safe for dogs. But, it's not a good idea to let your dog eat the peach pit. The pit can cause an intestinal obstruction. If a dog crushes a peach pit and eats it, then he will ingest some cyanide. But, he'd have to crush and eat a large number of peach pits in order to eat a toxic amount.
