From Cat

Toxins which can affect cats are numerous, but fortunately less common than occurs in dogs, mainly due to the cat's greater discriminatory powers over what they eat and when[1].

The most commonly reported intoxications are due to flea collars (pyrethrin and OP overdoses) and the majority of these are sub-lethal dosing requiring conservative therapy.

Their unique metabolism (an inability to glucuronidate many proprietary drugs) makes cats especially prone to intoxication by many pharmaceutical products.

Listed below are the more commonly reported toxins affecting cats.
