A colleague of mine has 2 senior cat ladies, Chica and Cookie. They are about 15-16 years old, a little overweight and do not move too much. So they are frequently constipated.

My colleague went to see the vet and she told her to give them olive oil and milk sugar. This does not seem to help.

Does anyone have experiences with that? I remember K&L's Porch had this surgery but something like that would be the last solution.
