They have tons of chemicals in them, in addition to the aloe. Maybe someone more knowlegable about chemistry could tell you which ones may be harmful if ingested. I'll guess it's O.K. but I wouldn't use them again.
You sound like a very careful person, who takes very good care of her kitties!"Water is the main ingredient and serves as a carrier and diluent for the other ingredients. Baby wipes also contain mild detergents mixed with moisturizing agents, fragrance, and preservatives. The detergents most commonly used are known as amphoteric surfactants, similar to those found in baby shampoos. Sodium diamphoacetate and coco phosphatidyl PG-dimonium chloride are primary surfactants used in wipes. These chemicals don't strip the skin of natural oils and also decrease skin irritation potential. Mildness is a prime consideration given that the wipe solution may be in contact with delicate skin around the anus and genitals.
Humectants such as propylene glycol and glycerine are added to prevent premature drying of the solution and contribute to skin moisturization. In addition, some formulas incorporate oils such as mineral oil, lanolin, or silicones that help to soften skin. Thickeners, such as cellulose derivatives like hydroxymethyl cellulose, control the viscosity of the finished product and keep it the right consistency.
Other ingredients include preservatives, such as methyl and propyl paraben, to ensure the solution does not support microbial growth. Fragrance is usually added to increase consumer appeal and to help over-come body odors, but fragrance-free products are also offered. Featured ingredients may also be added to increase consumer appeal. These include natural ingredients that are known to be kind to the skin such as aloe vera or oatmeal extract."http://science.enotes.com/how-produc...dia/baby-wipes
