My kitten is 13 weeks old and does not eat her wet cat food. Ideas?

 This title was/is on Reddit.com. This is my response on that social media website:

Dry cat food is sprayed with tasty stuff which can make it addictive almost. Without this covering it is like cardboard. I think it is fairly important that she eats some wet. What might work is trying best quality wet and heating it very slightly in the microwave. Also try wet food for elderly cats for a short time as it is smellier. Just some thoughts. Eating dry all the time might make her slightly dehydrated. It can cause urinary tract issues. If she is a rescue cat, she may have got used to dry food at the shelter.

I am not sure I am completely right but the gist is correct.

I will add a little bit of detail. It is not unusual on my research for domestic cats to become almost addicted to dry cat food because it appears to be tastier than some wet cat foods. It must depend upon the quality of the food as well but they do spray tasteless dry cat food with a fatty spray which makes it very tasty. And it probably smells better than some wet cat food as well. And they get in the habit of eating dry cat food only as this cat has.

I think a possible solution is to buy high quality wet cat food for elderly cats which is smellier than your typical wet cat food and then microwave it for a very short time say five seconds on full power. This will ensure that the food is smellier which is important as smell is how cats judge the palatability of food initially.

As stated, I think domestic cats should eat wet cat food as a default and then some dry cat food when appropriate perhaps at night for grazing. And the odd treat. But to feed dry only can, on the say-so of some veterinarians, cause mild dehydration because domestic cats don't compensate for the dryness by drinking more than they would normally drink. 

And if a cat is mildly dehydrated it can affect their urinary tract and it might predispose them to urinary tract health problems especially if they might, for some reason, become slightly stressed. Stress can cause to cystitis when combined with dry cat food only.
