Jack had diarreah 1 time 3 days ago. Got him back to eating and normal stools. But the same night he sneezed loud and alot. Restless all nite. But this morning little sneezes. Vet said 1/2 benedryl. Wow he swallowed it but foaming drooling. It tasted bad. He had uri 3 months ago due to stress of xrays and testing. Is this uri or just sneezing. Rating well looks ok. Sneezing is small now. Food allergies maybe. Harballs ? Really concerned. Trying to wean him off purina friskies wet food but he is stubborn loves fish flavors an chicken. Do cats sneeze? And could be ok.
