We came home from our weekend trip and she acted normal jumping up on the armrest. I fed her but she only licked the food a little. Tonight she acts like she wants to make a poop and goes to the litterbox and then hunches on the floor where she leaves droplets of liquid that are green brown. Twice she threw up already. She cries a little when she tries to go. I think I my have to take her to the vet tomorrow. I wonder if she is just constipated or if there is an obstruction. Her appetite had not been good recently and I tried many foods.
