I had exactly same problem with my cat. But, one day, I had a glass of water on the table that I forgot to drink, and I saw my cat sniffing and starting to drink my water from that glass. Since then, I kept that glass only for my cat, and he is drinking daily from there. You can try it also : take a glass, go in front of your cat and drink from it, fill it back, and give it to your cat to sniff. I sure she will use that glass every day. Some cats have more personality and they prefer a glass instead of those aluminium bowls
