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.
Depending on how long the fight has been in progress, your dog could have traces of the raccoon's saliva in any number of places. If the raccoon has rabies, your dog could pass it on to you if you have any sort of open scratch or cut or if you inadvertently touch your mouth or eyes with the saliva on your hands. He could also pass it on to one of your other dogs the same way.
