Enhance animal details cards

**Describe the bug**
In the cards for animal details there is no context provided like there is written 'G-Retreiver' but not what actually it is i.e the breed of the animal and same for other details too, also the UI is looking so odd such as on hovering over the "adopt me" button it's background color is changing to yellow and the text color is white which is obviously not visible and hence not user-friendly.

**To Reproduce**

I will fix all these small changes regarding the animal cards which are kind of bugs and also Ui/Ux changes to overall enhance the cards so that the users can have a better experience.
