What do you treat your critters with. I used to buy a can of tuna for the cats.

10. Sardines, butter, cheeseburgers.

That's what we supplemented our 23 year old cat's diet with when she was getting frail in the last couple years. She really, really loved the cheeseburger (just a small patty, with a quarter square of American cheese, then chopped up fine) but she'd eat a brick if you buttered it, and sardines were her personal heroin. Also buttermilk (which has very little lactose) and greek yogurt (which has almost none) and string cheese (no lactose), if we pulled off fine strings and let her play with them.

By then, we were happy as long as she was eating something, and as long as she was capable of eating, drinking and getting to the litter box, we were willing to continue kitty hospice as long as she was engaged and not in pain. She was never lactose intolerant, but we never gave any milk anyway. She was never very large (topped at 7.5 pounds) and was down below 4 at the end, but she pretty much beat feline kidney failure at age 19 thanks to stem cell research (she was a test subject.) It was a stroke that got her, after a very long, happy run.

We and her vets (especially her specialist vet) attribute her long life to good genes and us keeping to the kitty principle of obligate carnivore, with a reasonable amount of moisture in everything she ate. Spouse fed her kibble when she was a teenager (from 4 months until she was three) but she acquired a sibling who couldn't tolerate kibble, so she was on canned for most of her life. Kibble is really hard on cats; they're not equipped to process all the carbs.
