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.
Report Abuse. They are safe, but they are very high in fat. Pet stores (and actually now Walmart) sells something called Better than Ears. It's the same taste and texture of a pig ear, but it's much healthier for dogs. just now. Report Abuse. I think pigs ears and rawhide bones are fine as long as your dog is not a pig. i would not give them to a labrador for example because as soon as they have chewed it small enough they swallow it and that's when choking becomes a problem.
