Poor Fluffy! He could have eaten something rotten, could have a foreign body, could have pancreatitis, or could have a GI illness. I can give you a home remedy for him to see if that helps. I recommend withholding food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. Best of luck.

    Poor Baby. I can give you a home remedy to see if that helps. Withhold food tonight, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she refuses to eat the bland diet, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.

    Oh no, poor Momo! It could be that he ate something he shouldn't causing him to vomit. It could also be caused by a GI illness or a foreign body. If you can keep him indoors for the next couple of days, maybe in the garage, I can give you a home remedy to try before having to take him into the vet. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

    Poor guy. If he is still active and alert he may have just eaten something that has really upset his stomach. You should be able to wait until morning for an appt if he is otherwise ok and the vomiting does not continue past this point. Fast him for 12 hrs, only offering him free access to water. This will hopefully help his stomach settle a bit. In the morning you can offer him a small amount to boiled plain chicken and rice. If he takes it and holds it down, then you may wish to continue to monitor him for the next 24 hrs to see how things progress. Hopefully he recovers well and doesn’t get back into whatever it was that made him sick to begin with. Comb over your house for any evidence of him tampering with anything that may be harmful and also keep in mind that sudden Food changes that are not gradually done over the course of a week can cause symptoms like this as well. If he is still not better by morning then it is best to take him in to your vet to get checked out. I hope Phoenix is able to recover well. Best wishes and take care.
