The SPCA says its constables found 18 horses, 18 dogs, 15 birds, two cats and 104 fish in various levels of distress on Karin and Catherine Adams' property, east of Houston, last August.
SPCA Const. Debbie Goodine says the horses were living in unsanitary living conditions, lacked food, water and shelter, were underweight and suffered from poor hoof care and suspected parasite loads.
She says the other animals were living in substandard and unsafe conditions and faced serious medical and dental issues.
Goodine says the animals received extensive veterinary care and were moved to new homes.
The SPCA says the mother and daughter have been charged under the Prevention of Cruelty to Animals Act, as well as the Criminal Code of Canada, and are expected to appear in court on March 16.
