Mr. Fluffles

I will be having a little guest this weekend, Mr. Fluffles and I are going to give each other a try-out.
His owner brought him to the vet today, and I tagged along to ask questions. The vet is doing a blood test for kidney disease, which he told us is the most common problems in older cats. Mr. Fluffles is 14, and could live to be over 20.
The vet said he’s in good shape as far as he could tell from an exam. He has certainly lived in a very good home: his current owner has a degree in agriculture and used to run a farm.
I’ll take some pictures, but in the meantime, he looks somewhat like this: grey, fluffy and markings between the eyes.
He seems to have a very mellow disposition, which suits me very well, and maybe we already have a vibe: on the way home, I stopped at the supermarket and without giving it much thought, picked up two kinds of fish. Cat ESP.
