Name a common site for subcutaneous injections in cats.

The scruff of the neck is a common site for subcutaneous injections in cats because it provides a relatively loose and easily accessible area of skin that allows for effective administration of the injection. This site is often chosen as it helps avoid hitting major blood vessels or nerves, making the procedure safer and more comfortable for the animal. Additionally, the scruff allows for slight tenting of the skin, which is ideal for delivering the vaccine or medication subcutaneously.

Other locations may have their benefits but are not standardly used as frequently for this purpose in cats. The base of the tail is not typically preferred because the skin can be more fibrous and less pliable. Administering injections between the shoulder blades or in the inner thigh may pose additional challenges, such as difficult access or increased tension in the skin, which could result in discomfort for the cat. Therefore, the scruff of the neck stands out as the optimal choice.
