When I brought Shelby home from the breeder, the breeder told me that Shelby was eating only dry food. Since my other two cats eat nothing but dry food and Persi was raised from a Kitten on dry food, I continued to feed Shelby dry food. She was 8 weeks old when we got her and she is now 11 weeks old. The last few days she acts like she is having a hard time eating the dry food, turning her head and closing her eyes tight to crunch the food. Then, on occasion, she goes over near the litter box to throw up. After she throws up, she heads for one of the many water dishes around the house. I was hoping she could eat dry food like my other cats but maybe not? Now here is the strange thing about all this. She only throws up when eating the kitten food. She steals the adult food whenever she can and has no problem with that. I have since fixed the food situation so the adults cannot eat the kitten food and the kitten cannot eat the adult food. My adult cats have been so healthy on their dry food I never gave it a thought feeding the young one the same thing in the kitten version. The same thing being Science Diet Indoor Cat and Science Diet Kitten formulas. I have not yet tried wetting her food although I imagine that will be something I should do.
