The charity homes the animals, some of which arrived as they could no longer be cared for by their previous owner, at a centre in East Ardsley.
Regardless of how they end up there, the animals are cared for until a new home can be found. The RSPCA also offers advice to people who already own pets but may be struggling to cope with the cost of food or healthcare.
This week, they include handsome Bull Mastiff Billy, who is nine years old and is looking for a retirement home.
Here are all the cats and dogs currently being cared for at the centre that have not yet been matched up with the right owners –
13. Tala and Goose
Huskies Tala and Goose had a tough time before coming to the RSPCA's centre in Leeds, as they were both kept in cages for long periods of time - and suffered "a lot of neglect". After months of patiently waiting, they found a new home. But sadly, this was not to be their forever home and they are once again hoping to find a new family.

14. Angel
One-year-old Angel arrived at the centre in a "bad way", the team at the RSPCA explained - and was "absolutely starving". But after plenty of love and care, she now has a full belly and is a happy and healthy kitten. Angel loves fuss and attention, and would be keen to live with a playful family. | RSPCA Photo: RSPCA
15. Zeus
Zeus, a Staffie X, is a three-year-old bundle of energy and is looking for a family willing to offer unconditional love and keep up with his training. He can be unsure of other dogs so would suit a family that could help him feel comfortable when out on walks. Despite getting over excited at times, he loves a cuddle. | RSPCA Photo: RSPCA
16. Prinny and Davie
One-year-olds Prinny and Davie are brother and sister who came into the centre after living in squalid conditions. They would prefer a quieter home with adults only who have cat experience. | RSPCA Photo: RSPCA
