My cat is walking slowly and laying around in different places around the house that he usually doesn't. I opened a pouch of treats that he usually runs for but he just slowly walked over to eat them. He went outside for a while but just sat on the front porch in the sun. He is usually out there roaming for a while. I coaxed him back inside and brought some food and water over to him. He ate some dry food but I didn't see him drink any water. This isn't his normal behavior so I'm concerned. I'm not sure if he ate something that is making him feel sick or what. I haven't seen any vomit around. I'm monitoring him right now but wondering if anyone has any suggestions.
