My almost 17 yo cat had an excellent check-up at the vet's this week, including normal blood test results. Hooray! I've been reading up on care of older cats and I find that sometimes he does seem a little confused (do I want a snack or do I want XXX?) and drinks more water (his kidney function is good) and needs a step to climb up to the bed. But overall he's doing really well and this makes me very happy!
