Awwww, bet they're just wee balls of fluff at the mo
Can't wait to see them
I'd say no to putting in a cat flap though
We put one in for Misty & Mittens and since they're such fantastic mousers we get many 'presents' brought in for us through the cat flap - mice, voles, birds, even a mole ! They're not always dead either
Also, the ferrel tomcat (who visits us from time to time) has chased Mr Tumble into the house on occasion too so he can continue to beat him up
Oh and the wee Jack Russell from down the road frequently ends up through the flap when she's been chasing our kittens.
Might work if you have one of the auto-opening ones, but then you've got to have a collar on your cats - I always think that's a bit risky when they are hunters though incase they get stuck somewhere because of it.
But get those photo's on quick !
