I can't take in any more cats in right now as donations have been very low this year and lack of space.  We being a no kill shelter, the remaining cats still need daily food, litter, medical ect. Thanks for your much needed donations. Also, if you live in Stanislaus county and can volunteer, please meet me at this Petco and you can also donate there. It may take a week to answer your emails and I can't return long distant calls. Please speak clearly when leaving voice mails. We're also on Facebook. Search for kitty haven rescue in Modesto. Thank you.
