Hello all! I am new to owning guinea pigs, I have had my piggies for about 2 weeks now. Both piggies are males around 4 months in age, their names are Milo and Mason Unfortunately, when I adopted my piggies they had a URI that the current owner was not willing to treat. So, I took them to a trusted exotic vet near my location and they prescribed them antibiotics called Chloramphenicol Palmitate 2x a day for 10 days. Today was the last day of antibiotics, their URI seems to be recovered along with around one to two sneezes a day, but really only when eating their hay. Yesterday, I noticed someone was having clumpy poops, they are not very watery but shiny and soft enough to be mushed together into a big clump. I know the poo is coming from Milo and not Mason. Milo is also drinking loads of water. From reading on this forum, I have withheld all fresh veggies as of this morning to see if his poops become more solid. I called the vets and she told me it could easily be a side effect from their antibiotics. I was advised to take away veggies for 24 hours to see if his poops become more solid, but they are acting as if I am starving them. I have unlimited hay in their cage 24/7, I top off their hay 2-3 times a day to make it as clean and fresh as it can be and provide them with new pellets every morning. I feel as if they have become addicted to veggies since their owner before did not have veggies in their diets. Every time I walk or even reposition myself in my bed they start to wheek like crazy thinking I am going to be giving them veggies I feel absolutely terrible but I want their poops to get better. I ordered some powder bene bac probiotics that are arriving tomorrow morning. If his poops seem to be a little better I will try adding some powder to some parsley or lettuce for a little snack. I just need some advice, I feel terrible from withholding veggies for a day or two but it is for their own good. On usual I give them each 1/2 cup veggies in morning then 1/2 at night, therefore 1 cup veggies per piggy a day. Along with unlimited hay and a bowl of pellets. What do you all think? Also any tips for new owners appreciated thank you!
