Instructions
Carry the cat away from her kittens but close enough that she can still see, hear, and smell them. You don't want her to associate the antibiotic (and any connected discomfort or displeasure) with the kittens. If the kittens are less than a week old, wrap them in blankets or towels before removing the mother.
Tilt your cat's head back gently to administer a pill. Slip it between her teeth toward the back of her tongue. Hold her mouth shut while stroking her face and throat to encourage swallowing. Don't agitate, squeeze, pinch, or apply pressure to her nipples.
Fill a dropper with the recommended dose of liquid antibiotics. Holding your cat's head, insert the dropper between the teeth toward the back of her mouth. Depress the dropper slowly, giving the cat time to swallow. Again, don't agitate her nipples when you handle her.
Hold the cat until it has swallowed several times, whether you've administered the medicine by pill or liquid.
How to Give Antibiotics to Nursing Cats
You can give oral antibiotics to nursing cats in either liquid or pill form, although liquid is usually easier. The general technique for administering antibiotics is the same as for cats who aren't nursing, but pet owners should take steps to ensure the nursing cat and kittens are not harmed in the process.
