Hi! Thanks for using Petco Pet Education Center, formerly Petcoach! Although not normal, it is not terribly uncommon. It could be due to the anti-inflammatory/pain contro medications he was on or even stress from the procedure. Monitor him closely for now. If no improvement in the next day or so, have him evaluated by your veterinarian as anti-diarrhea medicationscan be startedat that time. Good luck!

    Hello, thank you for using Petco Pet Education Center, formerly Petcoach. Blood on the stool is not "normal" but I would not be concerned about this as long as long as it does not continue. If he keeps producing stools with blood on them and/or he is acting sick, then you need to take him to your vet for an exam.

    I'm sorry Tuck isn't doing well! Given that he's otherwise behaving totally normal, it should be fine to wait until Monday. Certain medications can cause blood in the stool, and if he's on any medications from the neuter, that could be the cause. It could also be that he has intestinal worms causing the blood. I would keep a close eye on his tomorrow, and if he starts becoming lethargic, the amount of blood in his stool increases, he stops eating, he vomits food, stops drinking, and/or vomits water, then yes I would take him into a vet ER. I hope this helps!

    Thank you for submitting your question regarding Romesh. I recommend that he sees a veterinarian. The blood is typically from the colon. It can be due to inflammation from the diet change or an intestinal infection. Other internal diseases such as pancreatitis can cause this signs as well. His veterinarian will evaluate him and determine if fecal testing or bloodwork are necessary. I hope this information helps!

New 2 year old cat. 4 days ago he was nuetered. He is eating fine but today has diahrea. Is it his food or from the surgery.
Hello and thank you for reaching out to Boop by Petco - and thank you for having your cat neutered! The diarrhea could be from his recent surgery. It could also be related to a diet change, or something such as intestinal parasites. I recommend keeping your cat's diet constant and monitoring for resolution of the diarrhea over the next week. If after 4-5 days his stool is still very soft, I recommend bringing a sample of his stool to your veterinarian who can analyze it for parasites. If your cat ever becomes lethargic, or doesn't want to eat or drink, he should be seen by your vet sooner. I hope this is helpful!

My kitten Kylo is 7 months old full breed Maine Coon has Mild Tricuspid Valve Dysplasia. He was 100 percent healthy. I brought him to be neutered on 12/14/18, he ate the first day. But then woke up on 12/15 with completely water poop (tan color) the
It is possible that he could have had a reaction to the anesthesia or just the stress of being neutered. Or it could be completely coincidental and it could be secondary to something else like parasites, foreign body, a sudden change in food, pancreatitis, an underlying infection, and much more. I would try to feed him some plain boiled boneless and skinless chicken and white rice. I would also try to start him on some probiotics. Your vet should be able to provide these or give you some recommendations. You can try some plain sugar free yogurt but the probiotics in this isn't as good as the cat probiotics because we have different bacteria in our gut than in cats. The next step should be to have him re-examined and likely have some bloodwork done. I would also make sure the vet has ruled out an parasites including giardia which is difficult to find on a regular fecal test. If your vet doesn't think there is a foreign body, they will be able to provide him with a good anti-naus

My 2 month old kitten has been having diarrhea for the last 4 days. Hence we immediately got his vaccination and deworming done. He was getting better but suddenly he passed very loose stools with mucus and blood in it. I have attached photos. The
This can commonly occur after intestinal parasites or stress from vaccinations. Your cat most likely need some antibiotics and possibly a probiotic to help get the gut health back to where it needs to be. Once this occurs the diarrhea should resolve. I hope this helps. Thanks for using Boop by Petco. Best of luck.

This morning my cat gave birth to 5 kittens now she is having diarrhea.. is this normal or not ??
Hello and thank you for reaching out to Boop by Petco. It is not unusual for animals to have some diarrhea after giving birth. As long as she continues to eat well, this should slowly resolve over the course of the next 3-4 days. If it does not, or if Naughtt develops any other unusual clinical signs, I recommend having her seen by a veterinarian, as an unrelated issue may be present. I hope this is helpful!

I have a kitten that has been having really soft watery poo ( diarrhea ) for about a week. so i started his worming yesterday by giving him 1/4 of a drontal tablet. However today i found some blood in the litter box and on the floor as he rubbed and
Thanks for using Boop by Petco! This really depends on a lot of factors. It depends on how much blood Tiger may be losing and if this is truly from diarrhea being caused by the parasites. If a diagnosis of parasites was established and you are giving the deworming as instructed by a veterinarian then it would be reasonable to see if this was just a one time episode of bloody stool and to have him examined if it continues. However, if a diagnosis has not been established by a veterinarian, I think it would be best to have a veterinarian look at Tiger as this diarrhea and bloody stools may be unrelated to parasites in which case it is not going to improve with the dewormer. Good luck and have a great day!

I took in a stray cat and on February 13th of this year I brought him to a low cost clinic where he was neutered and vaccinated. Now he is peeing and pooping in random spots in my house (he’s been inside well over a month and this is the first time i
It is unlikely related to neuter surgery since it has been over a week since the procedure. The going to the bathroom out of the litter box can be a sign of stress or a medical problem. The blood is concerning and may be related to the diet or an infection. You do need to have a vet examine him and check a stool sample for parasite and an infection. They can prescribe medication if needed. The longer this goes on, the harder it is to make them go back to the litter box You may also look into changing the diet to sensitive stomach formula to help and adding a probiotic that can be purchased at a pet store to help until you can get him rechecked.

9 month old male cat was neutered yesterday and is peeing blood. This has happened 2 times, an hour apart. He's not acting weird at all and he isn't acting like he's in any pain. He's not acting unusual when he pees, just leaving a small spot of dilu
Hi there and thank you for using pet coach to address your concern. It is not common to see blood in the urine in male cats after neutering. The blood yu are seeing may be from the incision site. In any case, I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

I got a 7 week old kitten on Thursday. He arrived and has had bloody diarrhea since. He has been eating kitten food and drinking water. I'm pretty sure he wasn't weaned from mom and was last nursed that day. He is playful and seems like a normal kit
Thank you for contacting Boop by Petco with your question about Prince. Congrats on your new kitten, but I'm sorry he isn't well! If he wasn't weaned and is now eating a kitten food, that could be causing the bloody diarrhea. I agree, it does look like his anus is protruding a bit. Given that he's eating and drinking and otherwise acting normally, it's fine to wait until the morning to wait to take him into a vet. He should see one first thing in the morning to get treated. Tonight, keep feeding him and giving him water, and keep him warm and comfortable. I hope this helps!

hello, I'm concerned about my 2 month old kitten. 6 days ago he went through surgery to get neutered and now that I adopted him i noticed that his bum is sensitive and is bleeding a little bit. Is that normal or no?
Thank you for contacting Pet Coach with your question about Buster! No, a sensitive and bleeding bum is not normal. It could be possible he is suffering from intestinal worms or impacted anal sacs causing this issue. I would take him into the vet tomorrow. The vet can diagnose the cause of this problem, and can treat him for it. Best of luck, I hope this helps!
