I loved reading Angel's story and want to congratulate you for your wonderful act of humanity in sterilizing the mother - she probably appreciated not going through any more pregnancies as well!

Please know that tulips and many other flowers and plants are extremely toxic for cats (and dogs too) and can cause serious illness or fatalities. Especially with the nice weather beginning - people planting gardens and some cats still go outside unsupervised. You can do a Google search to get the full list. Wouldn't want anything to happen to sweet Angel or his furfamily.
