First, keep those Easter lilies away from your kitties and pups! There are a number of lily types that are toxic to furbabies, Easter lilies being one of the most dangerous. Any part of the Easter lily can be toxic, even the pollen. Lily toxicity can lead to any number of life-threatening side effects, one of them being acute kidney failure. As you surely already know or can guess, it is simply safest to keep any and all lilies out of the home, well out of reach of your kitty or pup.
Other Easter goodies to keep away from your furbaby include chocolate, which is also toxic, as you all certainly already know. Don't forget the danger that other candies can pose as well, such as the sugar-free sort containing toxic xylitol. If you are giving or receiving Easter baskets that contain candies such as these, keep them well hidden away, so that hungry or curious furbabies cannot help themselves to a toxic snack.
It is also worth it to noting the danger of Easter grass. This stringy grass-like material often used as a filler in Easter baskets can be dangerous if ingested by a kitty or pup. It can lead to emergencies such as intestinal blockage, perforation, or laceration. Try not to use any such materials in Easter baskets. If you receive a basket with this dangerous fake grass material, keep it well out of your furbaby's reach and dispose of it safely.
