I have 3 rescue cats myself.
They are sweeties. I’m allergic to them though (the second group of two, not the other four). Wal-dryl every day for me now.
I've had mine for about 8 years now and haven't taken a vacation since I've had her. I remember how she was cowering in the cage when I first saw her and I vowed I'd never put her thru that again by boarding her for any length of time.
This weekend I'm going away for the first time and I've called up several friends with cats to be reassured that mine will be ok on her own for the time I'm away.........
I'll leave a light on in the kitchen and talk radio on in the background to keep her company.....
