Gressy is a 4 year old cat, who has calicivirus. Because of the inflammation in her mouth, she is in pain and twists her head sideways when she eats.
Because of the ear infections, Gressy ended up developing parasitic ear infections. Her ears are painful, which makes her feel bad every day!
Wet food like canned food would greatly help Gressy. Such food would allow her to replenish her energy, without suffering too much. This would increase her chances of getting in better shape little by little!
Our association is having a hard time getting members, so donations are not coming in. As people are afraid to lack, they do not help us, in spite of our appeals on the social networks.
So we have no budget to buy food for the cats. On my side, I can't afford to finance everything with my personal money forever. We need solutions, and fast...
