Say needle, and some people go weak at the knees. Tell them they have to inject their cat with a needle regularly, and they may feel they just wont be able to, especially because they fear they will hurt their pet. They wont. If youre among the needle phobic and are told you need to administer injections yet still dont feel convinced, keep in mind that you love your cat and want her to stay as healthy as possible for as long as possible. You can do this.
