Curiosity CAN Kill Dogs and Cats - Dangers To Watch Out For

What Poisons And How To Recognize The Signs Of Poisoning

Curiosity makes cats and dogs vulnerable to poisons because they have to play with or chew on everything. They can get very sick, very quickly and even die from poisoning if not treated quickly enough.

Chemicals: Here are a few of the common chemicals that are poisonous for cats:

1. Antifreeze. Dogs and cats like the taste and will lick it off of the garage floor. It can cause seizures and if enough is ingested, can kill a pet.

2. Rat poisons and insect sprays and treatments. If you treat your home with insecticides it's very important to keep your cat away from the treated area for several hours. If you spray inside of your home, thoroughly wash the cat's food and water bowls to clean off any insecticide residue.

3. Bleach, alcohol, gasoline, turpentine, lead, acid, garbage waste and paint.

4. Toads and salamanders.It will be evident by excessive foaming at the mouth and drooling.

5. If your cat or dog eats a bird, insect or rat that has been infected by a poison, it is likely that your pet will become ill, as well.

6. Wood glues such as Elmers Pro-bond and Gorilla Glue contain polyurethane and is very deadly. Even if only a small amount is eaten, it can swell in the stomach resulting in severe gastrointestinal problems which can cause blockages and require emergency surgery to remove the mass. Years ago my brother worked in a shop that re-upholstered furniture and his dog ate a tube of glue and died within a day.

Foods that can poison your pets

Keep these food items away from your pets

Other things besides plants and poisons can kill your pets. The following items are not to be taken lightly. Do NOT feed anything with these items to you cat or dog. They are NOT treats!

1. Chocolate. Just a little bit of chocolate can kill your cat or dog. Make sure to keep these treats out of sight and reach. A great article by a vet about chocolate and how much is deadly is at A tale of two chocolates: How much is too much and how to know

2. Xylitol. Xylitol is a sweetener that is extremely dangerous to your pet's health. Just a few grains of this sweetener can kill your dog or cat. Xylitol is found in toothpastes, sugar-less gums and other candies. Read the ingredients of all foods and products you buy, not only for your health and safety but that of your pets.

3. Alcohol. Many people think it amusing to give their pet alcohol, but it is very dangerous. Alcohol depresses the central nervous system, causing tremors, difficulty in breathing, and can cause coma and even death.

4. Grapes and Raisins. These are known to cause kidney failure.

For a more foods that can poison your cat or dog, go to people foods that poison pets.

Keep Your Pets Safe During Holidays

Holly and Mistletoe and many Lilies are toxic to pets.

During the holidays be especially careful with the plants and decorations you use. Mistletoe, many lilies, and holly all are toxic to pets - both cats and dogs.

Cats and some dogs also love to play with things that dangle such as tinsel, ribbons, and string. So be very careful what you choose to decorate with. Trees can be beautiful with the tinsel, which if swallowed can cause major problems such as blockages, which could even result in death.

For more plants and products to watch out for, check the following modules and have a safe and wonderful holiday season. In fact, keep all of these things in mind during the year as well.

      @anonymous: I'm so sorry to hear about losing your cat. With my cats and my rescue ( I have a total of 17 indoor cats. Since I can't have plants because they eat them and dig in the dirt around the, I make terrariums with lids. I love terrariums. To see some I have in my home, check out my lens, I also show several easy ways to make them. Bear hugs, Frankster

      Thank you for this important information. I had a beautiful cat that died because I didn't know easter lilies were poisonous. We don't keep any plants in our house any more after that--so I am glad to know the list.

      Very useful resource - one of my parents' dogs had an encounter with a toad once and it was not pleasant, although he did recover (the toad and the dog)!

      SquidAngel blessings for an excellent lens.

      I have a few of these plants (like lilies) in my yard, but the outdoor cats leave them alone. I grow pots of oat greens for the indoor and outdoor cats to nibble on. This is excellent information. Blessed by a Squid Angel...

      [in reply to Ramkitten] I think they mostly get what not to eat. The major problem I think is young kittens and pups. Also cats can walk on smashed plant parts then lick their paws. Which makes the other poisons (rat, anti-freeze, etc.) very dangerous. Indoor-only cats tend to eat any plant they can get to. If I walk in with a leaf stuck to my shoe, someone eats it and thankfully throws it back up. But so far nothing poisonous.

      Excellent information and really important to know. Do you think, when it comes to plants, that cats and dogs have at least SOME ... I don't know ... innate sense of what NOT to eat? Nightshade I know is one very toxic "family" of plants, and we had quite a bit of it on the farm we once lived on. None the dogs or cats ever touched it, but I wonder if that was on purpose or just luck. Anyhow, great lens!
