Hi
Welcome, its great to see you checking out this before you get them!
Guineas make lovely pets but do take a lot of looking after. Would one of your parents help you? It's also worth knowing that they live a lot longer than some small animals ( 4-7 years on average). I'm not sure how old you are but your parents may not want to end up looking after them if you leave home for college.
I got our first ones for my daughter ( then 7, now 10) but do help her to care for them. She does a lot herself but it would be too much to do it all by herself.( We feed/ check morning & night, 'spot clean' every 1- 2 days & do a full clean every 3-4 days, put outside/ on the floor for exercise most days, clip nails/ bath as required & cuddle! Would someone help you? Who would care for them if you go away for the weekend or a holiday?
I hope your parents are also looking at the information re care.
I don't think they smell as much as rabbits , but they do still smell, even with frequent cleaning ( well I can smell them as my sense of smell is very good, my husband can't!)
We have 6 & personally like the combination of neutered males & females from a rescue centre. I wouldn't recommend getting them from a pet shop, especially not 2 young males as they can start fighting as they grow up ( this happened to a friend of mine & I now have them neutered with females in 2 groups).
They are great pets, take your time to read & learn all you can first & think about whether its the right time. I'd love to also have chickens as well as the guineas , cats & rabbits & got excited & read up on them but eventually decided that its something I don't really have time for now & will try & do in the future.
Hope this helps, do post back with other questions if you don't feel you understand anything
