Unless I've drastically messed up my translation, it's a rescue litter from Berger Blanc... I'll translate the important parts of the ad.
"The breeder (rearing/breeding/rat farm) Sambou, located in Laval, welcomes a litter of baby rats (rescued? I presume it's franglais, because there's no equivalent in the Petit Robert French/English) from Berger Blanc. Born the 19th of February, they're ready for adoption.
"Springtime Special: adopt one rat and the second is half price! (of the same litter)
"Advantages of Rats:
-- It is ideal for young children as a first rodent because it is very easy to tame and handle. It is reputed to be one of the few rodents that doesn't bite.
-- It requires very little upkeep. Cleaning its cage 1-2 times a week takes only 30 minutes of your time and changing water/food takes less than 5 minutes a day.
-- Unlike most rodents, it gives off very little smell.
-- You can very easily teach it tricks like begging, recognizing its name, teaching it an agility course etc. The rat is a very intelligent animal.
-- It will return on its own to its cage, can do its business in a litter box and loves falling asleep in the warmth of your arms.
All our babies are raised with love and passion, that's why we reserve the right to refuse any adopter who is ill-informed or wishes to feed the baby to a reptile.
Will post the second half in just a minute.
