Hello and thank you for your question on Petco Pet Education Center, formerly Petcoach!

First question: It really does not matter when she eats but a matter of how much (how many calories per day). Eating twice a day is better than once a day so Misty does not get too hungry during the day and she can have a better blood glucose balance during the day. If you request a consult with me, we can go over calculating how many calories Misty should have in a day based on what food you are feeding her. A 4 pound increase in weight in a cat is like a human gaining 40 pounds.

Second question: Anal gland impaction can be caused by the anal sacs not emptying their contents normal and regularly. Typically, both dogs and cats express their anal glands when they defecate. If the diet does not contain a lot of fiber or the animals is dehydrated this can cause a back up and can lead to impaction. Sometimes animals are genetically predisposed for this problem. Sometimes owner may have to express their cat's or dog's anal glands manually every few weeks to prevent an impaction from happening. Adding extra fiber to the diet can help (plain canned pumpkin works very well).

I hope I have helped answer your question and if you wanted to chat further about the calories and food, I look forward to 'meeting' with you during a consult.

Best wishes and thanks again!
