URIs in cats have many causes and symptoms. Our resident vet explains the condition. I recently received the following question on cat health from a visitor to my website: My cat has a slight watery discharge from her right eye and it sometimes âcatchesâ dirt as it slides down her nose. I was just wondering if she has an upper respiratory infection and if so, what can I do about it. She doesnât seem to have any other problems at present. Occasionally, I wipe her eye with a warm washcloth.

Endorphins (contracted from endogenous morphine[note 1]) are endogenous opioid neuropeptides and peptide hormones in humans and other animals. They are produced by the central nervous system and the pituitary gland. The term endorphins implies a pharmacological activity (analogous to the activity of the corticosteroid category of biochemicals) as opposed to a specific chemical formulation. It consists of two parts: endo-and -orphin; these are short forms of the words endogenous and morphine, intended to mean a morphine-like substance originating from within the body.
