FFS, CP are becoming more like the RSPCA by the minute! Did they not offer to take the cat in? Am I misunderstanding or are they content to leave a cat and vulnerable kittens out in the none too warm April nights, at risk of harm and of the motehr becoming pregnant again fast?
There is no guarantee that she'll be fine at all if left... what CP mean is that they are sadly inunndated with cats and kittens and haven't the resources to help. Again.
I'm a rescuer - I recently took in (via MN as it happens) a cat which the CP had similarly abandoned to fend for herself having had kittens but at least there they took her in and vaxed and spayed her before chucking her out into gardens again. She's now safe and well on my sofa, sleeping. Poor mite is deaf, which the CP vet DIDN'T pick up on. They dumped her back into a garden near a busy road saying they could home her kittens but not her... unbelievable!
Can I help in any way, Pinot? Happy to find you a rescue which WILL get them all out of danger or to care for them all myself if needed and of course to provide you with all necessary references and reassurances.
