I actually have 13.
4 pairs:
Casper & Autumn
Bailey & Gypsy
Comet & Sapphire
Liquorice & Buttons
1 trio:
Fiver, Crunchie & Minstral
2 Singles:
Poppy and Oliver
Poppy and Oliver will hopefully be bonded once they've had their ops. Poppy has tummy probs and issues growing so my vet couldn't do it as she was so tiny. She's coming on nicely now though.
Fiver & Crunchie are brothers, hence the similaritys.
Sapphire is actually twice the size of Comet as he's a tiny nethie.
