We have house guests that brought their dog with them. The dog hates all cats. My husband says that we have to welcome our guests regardless of how the dog reacts to our cat, Peaches aged 11 months. Peaches has not eaten or used the litter box for 48 hours, except for 2 meat stick treats. Peaches ate one last evening and one today. I keep Peaches separated from the dog as well as I can in my small ranch home. Even when we all leave the house, she is in the exact same place when we come home, as she does not know when the dog will be back in the house. I know that Peaches is stressed. BTW, Peaches is very fastidious about her litter habits. If she wants her box cleaned, she will not go elsewhere. She will wait by her box to let me know that she is not happy. I clean her box a minimum of twice a day, so I know the volume of "output" to expect. Is her reaction normal? Should I be concerned by the lack of eating and litter box avoidance.
