ANTIFREEZE
Causes kidney failure. Those
containing ethylene glycol are very potable and readily ingested from
leaking radiators and puddles, especially by outdoor cats and dogs.
Early signs may included animal "acting drunk." Otherwise, no signs
are apparent until after 12 hours post-ingestion when animal may appear
collapsed from the effects of irreversible kidney failure. Sierra
antifreeze contains propylene glycol and is less toxic than regular
antifreeze but can still cause problems, especially if large quantities
are ingested.
CARBON MONOXIDE
Leaky vents and furnaces
will cause fatalities in pets as well as humans. Check routinely.
FROSTBITE
Prolonged expsoure to freezing
temperatures affects animals just like people. Even short exposures
to sub-zero cold can produce frostbite of feet, nose and ear tips. Provide
warm, enclosed shelter for animals housed outdoors. Wipe snow/ice off
feet from toe webs fo pets' paws after walks for outdoor activity.
ROCK SALT
Lime rock salt and calcium
chloride salts can produce vomiting and diarrhea as well as severe dehydration
if a large quantity is ingested. Store in enclosed containers and wipe
off feet of pets afer walks.
RODENTICIDES
(Mouse or rat poison) As
cold weather sets in, many furry friends move inside and poison and
bait is set out. Can cause fatal internal bleeding or kidney failure
depending on type. Effects may not pe apparent until it is too late.
Signs occur 2-14 days after ingestion. Most common rodenticides cause
hemorrhage by blocking Vitamin K which is necessary for blood clotting.
Signs include bruising of the skin, pale gums, coughing up blood, blood
in urine or stool. An animal may bleed to death if untreated. Rampage
rodenticides cause irreversible kidney failure and unlike anticoagulant
rodenticides metioned, there is no antidote. Always make sure rodenticide
baits are placed in areas where pets cannot get to them. Contact your
local veterinarian or emergency clinic if you even suspect exposure,
as animals will often appear normal until it is too late to treat them
successfully.
POINSETTIA
Contrary to popular belief,
the hybrid varieties of this plant which are used exclusively here are
not toxic. Ingestion of leaves can produce some mild vomiting and diarrhea.
