Hello, my name is Sami. I recently adopted my first Guinea Pig about 4 weeks ago. I adopted him from my local Petco store. His name is Chimichanga (Chim Chim, or Chimi for short ). He is about 6 months old and cute as ever! I took him to my Exotic animal Veteranarian for an exam on his health and all that good stuff and turns out she suspected mites because of the itching and biting his back, but didn't want to waste my money on a skin scrape and just went ahead with the 3 shots 7-10 days apart. My vet was very proactive on getting him healthy and only charged me for my visit and first shot of Ivermectin, my second and third shots were free along with a free nail clipping because they all loved him so much! I hated seeing him get his shots :sad:, but I would rather have a healthy piggie than no piggie! I know there is the Ivermectin you can inject orally or the topically on the skin, but my vet highly recommened the shot and I am very happy with the results of the shots. Chimi is so hyper all the time. I put him in his play pen and he runs around popcorning everywhere! He already knows the sound of my alarm in the morning and as soon as my alarm goes off he wheeks letting me know it's time to feed him . He is a little nibbler too lol. His first week he would always sleep inside his house and hide when I came in the room, but now he is always sleeping outside his house and on top of it! Whenever I have his food bags he wheeks and popcorns and puts his front feet up on the cage entrance. He is my little Chim boy and I love him so much ! He has an Awesome Mohawk going on on the back of his head and a few rosettes on his back which are totally adorable lol.
