A system and a method for pet monitoring that enable pet owners, vets or caretakers to remotely monitor and receive information about the health of a pet. The system and method can be useful in monitoring diet results as well as sickness detection. Components of a feeding device (3), along with a portable device(2) worn by the pet (1) and in communication with the feeding device (3), can monitor the pet activity level and type as well as the food and water given (type, calories and nutritional profile). A cloud device (5) may compile and may process collected measurements and perform an analysis based on said measurements and additional information stored in the database (551). The result of the analysis may be used to asses the health and wellbeing of the pet (1) in the light of his caloric, nutritional and energy needs, or issue warnings, notifications related to change of the habits to the owners, vets or caregivers.
