Give your pets shelter from strong sun, wind and rain, and ensure the opening in any pet house faces away from prevailing winds. Always make sure your pets have an adequate water supply.

See Safety and Security in the Garden and Creating a Child-Friendly Garden for more ideas.

Fun
If your animals like to dig, provide them with an area where this is allowed. Partially bury favourite toys to encourage them to dig there. Leave other toys to play with when you are out, so they do not become bored and get up to mischief, and provide scratching areas or posts as appropriate.

Poisonous plants
Many plants can harm animals if they are eaten, though most pets will usually avoid highly poisonous plants by instinct. The following are poisonous in whole or part so make sure they are not easily accessible to your pets in the garden:
Foxglove (poisonous leaves)
Oleander (all parts)
Daffodils (bulbs)
Azaleas and rhododendrons (all parts)
Rhubarb (leaves)
Lily-of-the-valley (leaves)
Rhus and euphorbia species (poisonous sap)
Laburnum (seeds)
Yew (especially dried clippings)
Caster oil plant (seeds)
