About

Première portée en 2009 mais ce n’est qu’en 2010 après beaucoup de réflexion que je me “lance” et officialise la chose. Mon site : ptits-rats-hippies.weebly.com

Avant d’être une raterie, je suis tout d’abord une propriétaire de rates, je tiens évidemment à ce qu’elles vivent dans les meilleures conditions de vie. Une rate n’est pas chez moi pour être reproduite, c’est un point auquel je tiens particulièrement.

Je prends soin de vérifier la généalogie des éventuels parents, s’il devait apparaître un problème de santé grave et récurrent/génétique, la famille s’arrêterait là. Les femelles ont au minimum 5 mois, elles ne feront idéalement qu’une seule portée. Si jamais les conditions me portaient à les faire porter une seconde fois, je respecterais un minimum de 2 mois minimum de repos, et une femelle ayant plus d’un an ne reproduira pas. Les mâles choisis pour rencontrer mes femelles auront, si généalogie connue, minimum 1 an, et si généalogie inconnue, minimum 18 mois. La reproduction des petits est encadrée : en cas de reproduction des petits, une discussion est engagée avec l’adoptant du petit afin que cela se déroule dans les meilleurs conditions possibles.
