Is There a Veterinian in the House?
You can shield you cat from disease and injury and can be treated if discovered early.
When petting your cat, observe his eyes, ears and mouth. Your observation may help catch a disease in it's early stages.
If your cat must take medication in the form of a pill, insert it into a ball of moist food and give it to your cat as a treat. Most cats are too smart and will eat the food and leave the pill behind. So you might need to hold your cat on your lap and open their jaw wide and drop the pill down his throat as far back as possible. Then hold their jaw shut and massage his throat. Sometimes you might even need to blow a small puff of air into their face so they'll swallow the pill.
Never give your cat aspirin - a single dose could kill your cat.
If your cat likes to eat wool or other fabrics - they might be suffering from pica. This is a when the cat is repeatedly craving for and ingesting non-food items. Make sure to take your cat to the vet right away if you notice this.
Signs of poisoning: listlessness, abdominal pain, vomitting, diarrhea, muscle tremors, lack of coordination and fee.
I hope that no one ever experiences this, it quickly becomes life threatening and should not wait for the symptoms to run their course - it may be too late.
(Boy, this was kind of a depressing one today - protect your cats and all pets for that matter.)
