@Marianne63 sorry to hear that you are feeling a bit down and depressed but hoping you are feeling better soon. I understand the grief of loosing a beloved pet and sometimes it's too much to deal with when you have other things going on in your life.
I used to work at RSPCA and their shelters often have wonderful loving affectionate cats looking for homes, especially at this time of year. If you are not too keen on a kitten, there are usually a lot of adult cats available for adoption that often getting overlooked for the cute playful kittens. I must admit, there were times were I fell in love with some adorable older animals there and it took all my strength not to bring them home with me (not to mention my husband would have killed me if I had :p ) and I would often be so exited when someone came an inquired about my favourite animals and wanted to adopt them. Good luck with everything and I hope you find a loving companion to comfort you on the next part of your journey xx
