Cats are typically less adventurous than
dogs when it comes to toxins, and the ASPCA Animal Poison Control Center warns that many of the most common toxins that cause
seizures in cats are due to human actions.
For example, some pet owners will apply a flea-control product made for dogs,
not knowing how dangerous that is for cats. Owners may also overdose the pet or
accidentally give the wrong medication. Permethrin is, as always, the most common cause of seizures
in cats. This can happen when a dog flea-prevention product is applied to a cat
or when the cat licks a recently treated dog, presses up against him or rests in
the same spot.
Other Problem Products
Ibuprofen can cause serious CNS signs at very high doses.
Depression, ataxia, coma and seizure top the list.
Tea Tree (Melaleuca Alternifolia) oil. This is most commonly
an issue when high strength preparations (often 100%) are ingested or applied to
Alpha lipoic acid is found in many supplements. At high
doses, it can cause hypoglycemia, seizures and hepatotoxicity.
Minodixil is used in humans as a systemic vasodilator and as
a topical treatment to stimulate localized hair growth. Any exposure in cats can
cause death. The most common signs in cats are pulmonary edema, pleural
effusion, compromised cardiac function and death.
Acetaminophen is a potent inducer of methemoglobinemia,
especially in cats. Seizures may be seen secondary to hypoxia in patients with
Baclofen is a centrally acting skeletal muscle relaxant. It
is extremely potent and can cause severe signs such as depression, coma, apnea
Bromethalin is a neurotoxic rodenticides, and cats are
significantly more sensitive than dogs. We can see a convulsant syndrome with
bromethalin that is often refractory to any type of long-term treatment, making
decontamination supremely important for these cases where dosages have the
potential to cause toxicosis.
