Guinea pigs (and all animals) should live in the clothing they are born in xx
I do agree with this statement regarding piggies as i would never dream of dressing mine up,they are comfy in there birthday suits

I dont agree with the whole putting little shoes on dogs and all the rest although,
In winter my cocker spaniels hair is still growing back so she has a jumper when we go out in the cold.
Also my dogs get walked rain/hail/shine so when its pouring rain all of my dogs including the big boys wear waterproof coats,
Its not cruel to do that i dont think as without it they are more likely to catch a cold which is worse.
Guinea pigs are models without the added clothes, unlike human models they dont need anything to look beautiful,just a set of piggy lips and a big bum imo:red
The clothing idea is another money maker invented by people who dont have the guineas real interests at heart.
Id also keep them away from weddings and big events just because of the uneeded stress it will cause.
Don't be put off asking questions,its better that you did as it means you care about your piggies welfare xx
