She's about a year and a half now and I took her for her vaccinations and general health check earlier on and the vet said she was overweight. She has got a bit of a tummy on her 
The trouble is, my elderly cat eats every three hours - just small amounts of a sachet and the younger one is finishing her food up 
My elderly cat likes the gravy, but often leaves the chunks.
I'm going to have to rethink my feeding routine.
Can I just buy gravy for the old one? They used to sell these tube things at my old vets, they were just gravy and she loved them, but we've moved now.
I'm also getting the kitten next Tuesday, so she'll need feeding too
