All cats have the strongest objection to having anything cold put into their ears. Therefore, if you use any lotion, let it stand in hot water, so that the chill may be taken off. If Condy and water is used, let it be tepid. Use a sponge, not a syringe, as the ear is a very sensitive organ.

If you see your cat constantly scratching her ear you may be pretty sure there is some hidden irritation. Make a funnel of a piece of paper, place some boracic acid powder in it, and blow down the ear. Do this a few times, and then wash out with weak Condy and water.

A very troublesome complaint in cats is canker of the ear, and one which is often not discovered until the mischief has fairly begun. If you notice your pussie shaking her head continually, generally to one side, you should carefully examine her ears, and proceed to clean them out with weak Condy and warm water. Be careful to dry them thoroughly. Canker may be considered as a symptom of general ill-health.
