My vet uses Gerber baby food i.e. chicken or beef for finicky eaters. She has cases and cases of this stuff in her clinic. My little Neena had the same problem and she suggested for me to try it. I also give Neena NutriCal and it is helping to get her appetite going. 95 % of the time she licks it right of my finger and the rest of the time I have to stick my finger into her mouth and she'll take it from there. I also use a small syringe for water. Neena doesn't like to drink water and will go without water for several hours. She used to be constipated too. When she doesn't drink enough during the day, I will use the syringe 2 or 3 times a day. Ever since, she has a much easier time with her digestion and goes at the same time (7 a.m.) every day. It works great. Her bathroom habits used to be so unpredictable. It's much much better now. Hope this helps.
