Olive oil works wonders too, if your baby eats wet food -
For a 3 oz Fancy feast can, use 1/2 teaspoon.
For a 5.5 oz Friskies, etc. can use 1 teaspoon.
Works best if you can either heat the oil first and mix it in, or mix it in and heat the whole food bowl JUST until warm.
Stir A LOT and let it sit for 5 min. or so so the oil can take on the food flavors.
Another alternative is canned tuna in OIL - save the oil and use that.
For grooming - 2 times of day are GREAT for this - in the morning, when you're snuggling him, groom him - it'll give him energy and rev up his appetite for breakfast.
Before bed - groom him, again it'll rev him for dinner and sate him to sleep.
Good luck!!! xxx
