I will be taking two of my guinea pigs, Delilah and Daphne to the vet tomorrow do to swollen throats. it started out with just Delilah with a swollen throat, and at the time swollen cheek, so I took her to the local vet. he gave her something called SMZ Oral Suspension, which cleared up the swollen cheek but didn't touch the swollen throat. he said she had non-contagious strep throat. I will be going to a different vet for a second opinion seeing as how now I have got two girls with swollen throats. they do live together, along with an older female and a neutered boar. neither of the older two have shown any signs of sickness or lumps at this time. I have quarantined the four of them from the rest of the household's herds (all total we have 13 pigs living here, in 5 different cages). I have removed all wooden chew toys from the cage for now just in case its something like splinters getting in they're throats. they currently are getting second cut orchard grass from the local feed store and the guinea pig pellets from KMS Hayloft. they live on fleece liners.
