Hi everyone, We just adopted our first rescue cat this week. He is 4 years old and came with a complete clean bill of health from the vet just last week. We are following all the shelter's re-homing advice and he is settling in brilliantly. Falling asleep in our laps, always wanting to cuddle and play. We have also kept him on the exact same diet he was on at the shelter (and before that, I think.) Expensive high-quality dry cat food, twice a day. We don't leave out anything else he could eat. He only picks at his food, but he has been eating - we just put it down to a little new-home stress and figured he'd be fine. But twice now in the last three days he has thrown up, quite aggressively, and it looks like he's swallowed his poop whole. It would explain why we rarely see anything in the litter box. We keep the box in a nice quiet private area of the house with the same chips he had at the shelter. He has used it once or twice so he's clearly not got a problem with it. So our question is why might he be doing this when he seems otherwise completely fine and is proven healthy? And also, how do we stop him from doing this? Obviously when we're home we can scoop it up right away, but some days we are both at work for 4 hours or so, and we have no idea how to stop it then. Thanks in advance for your advice! From, two confused new pet owners!
