Pet's info: Cat | Mixed Breed | Male | neutered | 6 lbs
Our 9 yr old male cat is smacking his lips/mouth x 6 days when eating wet food. No issues when eating dry food. In September had his right eye removed due to glaucoma caused by an infection. Since June 2020 his appetite has been reduced d/t pain related to the glaucoma abd possible stress. Post-surgery he has been stable at 6 pounds and eating 3oz/day. Is his intake at 3oz/day ok? and is mouth smacking related to his decline in appetite or another illness?

Hi and thanks for your request.
Mouth/lip smacking is usually related to nausea and decreased appetite could be due to that as well. The quantity of food would depend on the type of food you are giving /caloric content, so more informations about it are needed to be able to give you more specific advices.
